Braid Test Results

December 9, 2016

The following tests were done in Tampa, Florida by Aquaholik. RCW’s compilation started on the 4th quarter of 2016.  The results of the tests shows that we are well within paulusfishing‘s tests results margin of error. The only difference is how the diameter of the line is measured.


Diameter of the line is computed by Density = Mass ÷ Volume. Density of braid is a known value based on Honeywell’s website. The line is then weigh to get the mass. Once we know the mass, we can then compute for volume. And once we get the volume, we can easily get the diameter of the braid since volume is equal to pi times radius square times the height.


(What’s amazing is that our results is generally within 5 percents of Paulus’s results, all without actually measuring the line’s thickness. In fact our result is what you get when you try to squeeze the braid into a perfect cylinder whereas Paulus just average the line’s width and height since braid is flat when you try to measure them.)


S/W is an indication of the quality of the line. A high S/W means the line has a good strength to diameter ratio. It’s a ratio of the ABS of the line and the mass of the line per ft. Therefore, it is a strength to weight ratio.


To test the line a 10 ft section is measured. Then as straight as possible without introducing any twist, the line is loaded in the tester and test the ABS. The two section of broken line is then coiled and weigh on a precision scale. It is then divided by 10ft to get the line’s mass per ft.


FINS 40G 45# test
Got a 44ft samples of  Fins 40G 45 lbs test as well as two PR knots from RCW.
Fins 45# on left and 40# JBraid on right (chartreuse)


By look and by feel, the Fins 40G in 45lbs test is thinner. I cut a small piece and dunk it under water and it floats back up. So it doesn’t sink which means that it’s density can be no greater than water which is 1gr/ cubic cm. JBraid 40lbs has a mass of 29.6 mg/ft. I weigh all 44ft of Fins 40G 45lbs and divided by 44 to get a mass of 27.5 mg/ft.


So we have:
JBraid 40lbs  : 29.6 mg/ft —> .381 mm line diameter
Fins 40G 45lbs : 27.5 mg/ft—–> .367 mm line diameter.


Fins list this line diameter at .229 mm. Even if Fins 40 G45 lbs has a density of 1g/cubic cm, it’s diameter would be at least .341 mm.


So I did an initial ABS twist. And this is where I run into trouble. Using a 10ft section, I had to twist the line on to the two holding pins which gradually increases the tension until we get to the big 2 bollards.


Twisting it 8 times means the twist travels down the line 8 times. And another 8 times add 8 more until we get to the PVC bollards. As careful as I was, I can still feel a slight bump from the twisted line that did not unwind completely. I went and tested it anyway not sure how much the twist would diminish the strength. I got 44.80lbs, which is not remarkable considering the mass and Fins claim that it’s average unknotted strength is 61 lbs.


Let’s test the PR and this will confirm or denied my initial ABS test due to twist affecting the line strength. At 52.5lbs, the PR knot still did not break but the scale went no further. This indicates slippage either at the knot or where the line was wound around the metal pins and held with just a rubber band since the tension at the end of both metal pins are minuscule due to the number of turns.


I examined the knot and sure enough, it started to unravel. I took a video and then a screen shot: At 52.50lbs

I continued the video and continued to crank the handle and made slow progress with the knot gradually slipping but I got it to break at 56.50lbs. The knot eventually broke. This invalidate my initial ABS test and showed that twist can seriously affect the line strength.

So now I have to change my method of ABS line testing. I moved the bollards about closer to about 18 inches apart. I then started at the mid section of the 10 ft samples. I laid a perfectly straight 18 inch section across the bollard and carefully wound it one time on each bollard. Now we have the twist moving toward the ends and not at the middle of the line where the tension is the highest. It was a success. I took a video of it and the line broke at 60.50lbs. Bravo FINS, you actually did not lie about the ABS!


So we have SW of 60.50/27.50 = 2.20, remarkable indeed. And with a PR knot strength of 94%, the PR is indeed the king of all knots.


Actual Breaking Strength video of FINS 40G 45#, line broke at 60.60#

Ok, PR knot take two. Might as well test the other sample that was tied. After carefully loading the knot by loading a straight and kink free mid section first, I was confident that the test will be as good as the first results of 56.50lbs.


Here’s the last 30 secs of the test when the knot slipped free at 53.40lbs:


picture of the PR that slipped at 53.4lbs.

While unwinding the last 25 ft from the tight coil that I had formed, I ran into issues where the line would not unwind smoothly. I get bumps that ultimately reduced the ABS by 25 % as shown by the first initial ABS test.

UPDATE: December 5, 2016
Maxcuatro 30#, 40#, 50# and Jerry Brown blue 30# solid


The 30# maxcuatro braid has a remarkable S/W ratio of 2.44, the highest I’ve seen and I did two tests to confirm it. The line looks pretty ordinary, like Spiderwire Stealth or Stren Super Braid in 10 lbs but it is about 20% thicker. Line is shown PR knot to 80 lbs leader and next to JBraid in 10 lbs.

ABS and line mass test 1: 43.30lbs and 18.3 mg/ft
ABS and line mass test 2 : 42.45lbs and 16.9 mg/ft
That gives me an average S/W of 42.88lbs/17.60 mg ft = 2.44  , well above the good average of 2.0


One FG knot test at 34.65/42.88 = 81 %
One PR knot test at 37.90/42.88 = 88 %


Basically this line has the same FG knot strength as 30lbs Suffix 832 but it is 20% thinner in diameter. The 40# maxcuatro and 50# maxcuatro is almost the same line in diameter and strength:
40# maxcuatro has an ABS of 58.80 and a line mass of 24.90 mg/ft for an S/W of 2.36, again, exceptional
50# maxcuatro has an ABS of 59.90 and a line mass of 25.60 mg /ft for and S/W of 2.3.


I weigh a 5ft section of the 40# maxcuatro again and got 125 mg/5ft = 25.0 mg/ft so maybe you did sent the same line. Did two tests on 40 lbs Maxcuatro. Shorter PR yielded 87%. Longer PR yielded 92%. Line is breaking deep inside the knot both time. Not the mainline failure that you get with 100 % PR knot.So the smooth texture line does better on the PR knot than the rougher surface. FG knot test in 40lbs is even worst. Two tests at 36-37lbs, only 62% knot strength. FG knot with bobbin finish brought it up to 41lbs, still bad at 70%. So this line does not have good knot strength.


JB solid blue 30 lbs
ABS 44.90 lbs and a line mass of 20.4 mg/ft for and S/W of 2.20.

UPDATE: December 19,2016
Jerry Brown 30#, 40# solid

Jerry Brown Solid White 30 lbs:
Two tests (33.90, 33.50) lbs & ABS 33.70 lbs


Line Mass 19.80 mg/ft
S/W 1.70 Not very good compared to the blue solid Jerry Brown in the same lb test.


Jerry Brown Solid White 40 lbs
Two tests (62.70, 58.40)
ABS 60.55 lbs
Line Mass 31 mg/ft
S/W 1.95 lbs
One PR knot test 53.50lbs/60.55lbs = 88.36 %

UPDATE: April 06, 2017
Sent more samples to Aquaholik for testing
Daiwa JBraid 20#, 30#, 40#, 65#
Spiderwire Ultracast 20#, 30#, 80#
Spiderwire Stealth 20#
Fins 40G 25#
Fireline Crystal 8#, 14#, 20#, 30#
Superfireline (Japan) PE 1.2

JBraid Line up

Okay first up is J braid High Vis Green in 20 lbs
This sample from RCW has a mass of 17.90 mg/ft, making it almost the same as my sample of moss green J Braid 20 lbs test which has a mass of 17.50 mg/ft.
This sample has:
mass 17.90 mg/ft —-> diameter = .0117 in or .296 mm
ABS (32.15, 31.90) of 32.03 lbs
S/W 1.79

FG test 1 : 29.60lbs (15 wraps, 10 alternating half hitches, then tighten)
FG test 2 : 30.25lbs (16 wraps, 10 alternating half hitches, then tighten)
FG test 3 : 31.50lbs (16 wraps, one half hitches, tighten, then 9 more alternating half hitches)


I thought I found a better way to tie a stronger FG knot by not tightening until the end to keep the wraps tight but it did not matter as the above test shows.
I was surprised by the high result of the first FG knot so I did a video on the second and third test:


Daiwa JBraid 30 lbs test
ABS (50.10, 54 lbs) 52.05lbs (almost the same as the metered version)
Line Mass 21.50 mg —–> diameter = .0128 in or .325 mm (same as the metered JBraid 30lbs)
S/W ratio 2.42 (excellent making this the best bang for your bucks)
FG (37.0. 36.7 34.75) 36.15lbs 70% knot, same FG knot results as JBraid 30lbs metered.


Daiwa JBraid 30 lbs PR knot test
Only 39.70lbs. I need to work on my PR knot and make sure that it’s not my technique that is the problem. Loosely wrap spaced out then followed by medium tension close wrap, then a high tension overwrap over everything. For the finish, one half hitch, dowel tighten, then 24 alternating half hitches followed by 4 turn reverse uni finish. I thought the PR looked good. It did not slip but the result of 76 % is pretty low for a PR knot.


I need to back off the tension on the bobbin. I think I’m making it too tight for fear of slippage.


40 lbs JBraid HV green.
This one was a disappointment.
ABS (48.00. 45.80) = 46.90
Line Mass 27.35 mg/ft —–> diameter of .0144 in or .366 mm
S/W = 1.71
FG 39.90 / 46.90 = 85 %
Good FG knot strength but you might as well use 30 lbs J Braid since it’s thinner and has a better ABS (but 10% less FG knot strength).


Fins 40G 25lbs
From the Fins website, this line has an ABS of 42 lbs and a diameter of .008 inches. From our previous testing, we can say with confidence that their ABS estimate is dead on. 15lbs did indeed breaks around 26lbs and the 40lbs did indeed break at 61 lbs. Their published diameter however, is way under the actual diameter. We found the actual diameter to be 50% greater than the listed diameter.


We test the ABS twice and got 39.80 lbs and 41.25lbs for an average of 40.53lbs. The video evidences are below. So Fins is dead on again in their estimate of ABS of 42lbs and I’m sure that they use IGFA equipment to test their line and arrive at that number. What does this mean for us? It means that the home made equipment used in this thread is within 3% of the IGFA equipment!


The numbers in red are from our test equipment and we have the 25lb and 40lb on video as proof!


                              Fins Tests          Our Tests

Fins 40G 15#       26                       26.8

Fins 40G 25#       42                       40.53

Fins 40G 45#       61                       60.5


first test ABS fins 40G 25#

second test for ABS fins 40G 25#

ABS 40.53lbs
(test 1 39.8# + test 2 41.25# ÷ 2 =40.53# )
Line Mass 23.30mg/ft —> diameter .0133inch
S/W = 1.74


To put this in perspective, the JBraid 30 lbs is 3 times cheaper and it is smaller in diameter and has an ABS greater than 50lbs for the metered and HV green version. Yes, better S/D ratio at 1/3 the price.


PR knot test 34lbs / 40.53 = 83.90 %. Note the line broke before the knot. This usually indicates 100% knot strength but what happened is that the twist use to create the PR weakens the mainline just before the knot. That section is twisted heavily when you form a PR.

JBraid 65 lbs test HV green
ABS     70.80 lbs
Line mass 44.40 —-> diameter = .0184 in = .466 mm
S/W 1.59


At first analysis, this line falls into the theory that it’s expensive for manufacturer to use good spectra material in the higher lb test since they are basically charging just a little bit more per yds whether it’s 10 lbs or 65lbs but they are using 3-4 times the materials. So for the higher lbs test, it makes more economical sense for manufacturer to use a cheaper grade of spectra.


I was able to redeem my PR knot skill. This time I made sure that the bobbin is not spinning around twisting the braid unnecessary. I was able to achieve 67.50/70.80 = 96% PR knot strength.

But the real surprise was the FG knot strength. An astonishing 65.10/70.80 = 92% knot strength. That is unheard of for line class whose ABS is 70lbs. To put this in perspective, the previous best FG knot strength in the 70lbs line class was Berkeley Pro Braids 50lbs (55.10/71.90 = 77%).


Suffix 832 50lbs FG knot strength = 47/70.40 = 67 %
Suffix 832 65lbs FG knot strength = 58.63/84.00 = 70 %
Suffix 832 80lbs FG knot strength = 61.90/96.60 = 64 %
Power Pro 65lbs FG knot strength = 43.95/80.20 = 55%


This is the third time in a row that JBraid (20, 40, and 65lbs) with lower than average S/W ratio (below 1.80), performs extremely well with FG knot, whereas the 30lbs , which has very high S/W > 2.4, has FG knot strength in the 70% category.


So if you are jigging offshore and use FG knot exclusively, you might want to compare FG knot strength/line diameter when making your decision because the strongest line doesn’t always have the strongest knot strength.


JBraid in 65lbs is about the same thickness as Power Pro 65lbs. It is 10 lbs weaker in ABS but it has an FG knot strength that is 21lbs better!


Spiderwire Ultracast Invisibraid 20lbs
Similar strength and diameter to JBraid 30lbs and similar FG knot strength. 30lbs JBraid is slightly thinner and stronger but Spiderwire Ultracast Invisibraid 20lbs has a pound or two better FG knot strength.


ABS ( 47.90, 50.80 lbs ) = 49.35lbs
Line Mass (23.90, 24.90) = 24.40 mg/ft —> diameter = .0136 in = .346 mm
S/W ratio = 2.02
FG knot = 39.33/49.35 = 80%


Cross reference with Paulus test results:
ABS            =   50.38 lbs —-> +2%
Diameter    =    .334 mm —–> -4%


ABS test 2

Line Mass for both tests

FG knot test 1

FG knot test 2

Fireline Crystal 8 lbs
A hair stronger than my sample. Same mass therefore same diameter. Berkeley have great quality control is all I can say.
ABS (23.60, 24.65) = 24.13 lbs
Line Mass 10.8 mg/ft —> line diameter .230 mm
S/W = 2.23
FG knot (20.90,19.75,19.35) = 20 lbs = 82.9% FG knot strength


Paulus Just Fishing test : ABS 22.37 lbs, line diameter .227 mm


Fireline Crystal 20lbs
This sample is superior. Mine is a total piece of crap. First bad line I’ve gotten from this seller on EBAY. ABS is not that bad but knot strength on mine is horrible. Probably explains why it separated on an Amberjack. Glad to see that genuine sample from RCW has good ABS and FG knot strength.


ABS  50.00lbs
Line mass 28.30 mg/ft, line diameter = .372 mm
S/W ratio = 1.77
FG knot 39.10/ 50lbs = 78.20 %


For comparison, Spiderwire Ultracast 20lbs has similar texture, slightly thinner, and almost the exact same ABS and FG knot strength.


ABS test:

FG knot test

Super Fireline Japan PE 1.2 (similar specs to Fireline Crystal 6lbs)
ABS (18.50, 17.95) = 18.23lbs
Line Mass (7.8, 8.9) = 8.40 mg/ft
S/W ratio = 2.17


FG knot (15.5, 16.75) = 16.13/18.23 = 89%


There seems to be some variability in the mass but the weakest section seems to break around 18lbs in 2 test. Excellent and consistent FG knot strength.


ABS test 1

ABS test 2


FG test 1

FG test 2

SuperFireline Japan PE1.2 has better FG knot strength than 6 lbs Fireline Crystal.


Fireline Crystal 14 lbs.
This line has variable diameter thru out a 50 ft section. It’s strength to weight ratio is above 2.0 but it can break anywhere from 33 to 41 lbs.
ABS Test 1 : 33.10 lbs  Line Mass Test 1 : 16.20 mg/ft
ABS Test 2 : 41.60 lbs  Line Mass Test 2 : 20.80 mg/ft
ABS Test 3 : 41.45 lbs  Line Mass Test 3 : 18.60 mg/ft
ABS Test 4 : 35.50 lbs  Line Mass Test 4 : 17.20 mg/ft


FG Test 1 : 30.25 Line Mass 17.20 mg/ft
FG Test 2 : 30.15 Line Mass 17.20 mg/ft


FG knot strength = 85%?(It depends if you tied it on the thicker or thinner section)


Fireline Crystal 30 lbs test:


This line is quite thick. It has the diameter of most 60 lbs braid.
ABS ( 74.80, 68.80, 70.10) = 71.23 lbs
Line Mass = 44.00 mg/ft, line diameter = .464mm
S/W = 1.62
FG knot (39.20, 39.50) = 39.35 lbs —> 55%


Note that the FG knot strength is the same as the thinner 20 lbs Fireline Crystal due to poor knot strength percentage. Tried one PR knot and it failed at 42 lbs. So the verdict on this line is….use the 20lbs Fireline Crystal.


Jerry Brown Solid 30lbs Yellow
ABS (43.15, 38.00, 41.60) = 40.92 lbs
Line Mass = 22.30 mg/ft —-> line diameter .331 mm
S/W = 1.83
FG Knot ( 26.45 , 27. 600) =  27.03 lbs   —-> 67%


Spiderwire Ultracast 30lbs
ABS (52.4 , 52.9) =  52.65lbs
Line Mass = 27 mg/ft
S/W = 1.95
FG knot = 44.73lbs


Spiderwire Ultracast 80lbs
ABS > 114.00 lbs exceeded scale max capacity
Line Mass = 70.70 mg/ft —-> ABS ~ 130-140 lbs  (Based on Paulus test, the 65 lbs has an S/W around 2.0 and broke around 115 lbs)
FG knot = 90.40 lbs

UPDATE: June 15, 2017

Sent more lines to Aquaholik for testing.


We are going to compare Saltiga boat braid VS J braid, test the ABS and KBS of power pro in most sizes and colors including Super Slick and Maxcuatro, and complete our Suffix 832 testings. There’s even JB Hollow and Tasline from down under.


The Tasline we tested was such a disappointment based on Paulus’ results and the advertise diameter to strength ratio used by dealers in Australia and New Zealand.


Below is an exlanation of why Paulus’ diameter is not correct.


Now I will explain why his diameter for the lower lb test can not be correct. When you double the diameter, you increase the volume 4 times. That mean the strength is also increased 4 times. Put 4 strand of 10 lbs braid on the machine and test it and it will break at 4 times the strength of the single strand. Reweave those 4 strands into a single strand and you will find that the diameter just doubled. Look at his chart and my chart. Increasing the diameter 1.4 times and the strength also double.

Now look at the diameter of the thinner tasline. Take that and look for one that is 1.4 times or twice the thickness and see if the strength increase twice or 4 times. It doesn’t.

Also all spectra and dyneema must have a density no greater than .97 . That means for tasline to have such a small diameter, it must have a similar corresponding mass. There is no easy around that. The line floats. So it’s density is not greater than 1. Based on the mass and his ABS, the S/W is greater than 2.8. That exceeds the property of spectra! See the 360 tuna thread on strength of fishing line material. So you see, the diameter measurement for the smaller test can not be possible. It violates all known property of spectra.


Paulus’ or Paulus’ friend set the record straight with regards to our testing.


This is Tasline Elite White, the latest incarnation of the Tasline braids. Yes, the fact that manufacturers can change the fibres, the factory where the braid is woven, and the weaving process but still call the line by the same name is highly disconcerting. Paul does not recall testing this braid, so it will be very interesting to see if it stacks up against his original. One good thing from all this testing is that at least anglers now have an idea of what they are getting in terms of actual ultimate strength (breaking strain).


Paulus then tested the new tasline and this is what he said


Tasline Elite White 30 lb (From Busted Fishing) = ultimate load = 41.46 lbs. So this would appear to be not the same line as the Tasline Original, and the quoted ultimate load is too high (by 18%). This confirms your results.

FG knot with 16 wraps, 7-wrap Rizutto finish, 45lb Schneider clear line, and 30lb Tasline Elite White = 30.75 lb (74.8%). Your FG knots must be slightly better than mine, though we only tested one case.


Basically, Paulus wants Tasline and its dealers to stop using his website and his results to market the new tasline


I believe that Paul has contacted Busted Fishing to ask that all references to his Just Fishing website and the Paulus braid test results be removed from their website and sales literature. He feels that the Tasline Elite White braids are not the same lines as the original All White braids (whose test results are given on his website) since, after initial testing, they are showing considerably lower breaking loads.

The Power Pro Super Slick samples we received was fairly consistent line that is just average or below average in term of S/W ratio. The 40 lbs Super Slick Blue is a bad sample with high variability: 38.40/25.5 mg/ft, 44.70/27.1 mg ft, and 41.90/26.0 mg/ft. That is an indication of a bad weave and bad material. The 40 lb Super Slick in green also have bad S/W.


The 50 lbs SS blue also has high variability : 63.10/ 34.10 mg/ft, and 56.90/31.70 mg/ft .


The 30 lbs Super Slick in blue is much better at 46.10 lbs/22.20 mg/ft. So it might be a crap shoot which line you will get. The 30 lbs line  is stronger and thinner than the 40 lbs version. The 10 lbs Super Slick in green is a disappointment with an S/W of 1.66 —- 20.53lbs/12.40 mg/ft. The 65 lbs Super Slick in green is actually very good with and S/W of 2.12 —->87.10 lbs/41.10 mg/ft.


Aquaholik (Lee) also tested a new batch of samples of Maxcuatro

UPDATE: Sept 25, 2017

We received Yozuri samples from Chris Brown regional sales manager of Yozuri America for an independent testing of their superbraid. It took sometime to test the line and update this article due to hurricanes and life getting in the way.


We put yozuri 15# side by side with ocea ex8 for a “feel” comparison. Yozuri felt like the older suffix performance braid. Felt thicker than the ex8 pe2 which is rated 40#.

top: shimano ocea ex8 pe,2 bottom: yozuri 15#


the first test on Yozuri yield a 37.9 / 14.5  – mg = 2.61 S/W which indicates it is a good braid. It feels thicker than the ocea ex8 40# but it is thinner considering the mass and definitely stronger. Ocea ex8 is by far way smoother though.

yozuri 15-40# are 4-strand 


YoZuri SuperBraid 20#

Second test was 36.1 line mass which average out to 14.2 mg/ft which is better than spiderwire stealth camo 15 – the strongest 15# braid we have tested. The Yozuri 15# is also thinner than shimano ocea ex8 pe2/40#.


Yozuri 20# came in at 42.35# ABS and 17.4 mg/ft. SW = 2.43 – the same mass as braid 20# but 8-9# stronger. Line diameter is .292mm.


Yozuri 30# broke at 50.20# with a line mass of 21.6 mg the same as Jbraid 30#, S/W = 2.32 diameter is 0.325mm same as Jbraid 30#.


so far it is a very consistent braid.


Youzri 50# is soft and smooth, it is almost like a different weave. This is due to it being 8 strand. It has 35.5 mg/ft and SW = 2.29, diameter is 0.417mm about the same diameter as JBraid 50# and Jerry Brown 40# solid/hollow but breaks 20# higher.

yozuri 50lb is 8-strand


YoZuri SuerBraid 50#
