braid breaking strength

[puppet]

So,
Last season I used 55 lb daiwa samurai. The previous 5 years 50 lb power pro.

I have never given my mainline much thought....like I have, never really
had it tested on a fish. Sure, I have had mainline failures with structure,
but overall I have never felt like the line under performed.

I switched to samurai last year out of curiosity and noticed some
differences in performance.

1. it seems to cast better....just an impression...no scientific tests.
2. I noticed that the line broke easily when popping wind knots. Like, the
same technique on power pro does not cause a failure, but trying it on
samurai, causes an immediate failure with barely 10 lbs of pressure.

So I decided to test the break strength of both lines.

1. multiple tests where a 5' length line was tied to a cleat and to a digital scale
2. I didn't count knot failures....just failures that occurred in the middle
3. line was fresh from the spool....not ever used.

50 lb power pro - failed consistently at 30-33 lbs.
55 lb samurai - failed consistently at 27-29 lbs.

both surprising and disappointing.

Has anyone else found the same mismatch of advertised and actual breaking strength?


I didn't count the knot failures, but the knot failures happened at a
much lower threshold....like around 18-20# which may suggests a
poorly tied knot.

I would say I did 5 tests for each line....and 1 of the 5 broke at the knot.

It was just a quick comparison. Not extremely scientific....but if its
happening with brand new line...kind of makes you wonder the
strength of line that has been around the block.

If anyone can confirm or disprove my findings, I would like to know.

perhaps I got 2 bad batches of line?
