Test Your Braid!

Before retiring 5 years ago the company had a lab that I could use during lunch to tensile test using a Instron machine, very accurate.

The Instron recorded elongation (stretch) yield ( starting to stretch) and break strength. 

The factor the impacts line strength more then anything else is rate of pulling force. For example setting the rate+of force at .25” per second the data is very different from 2” per second. The slower rate tends to cause line breaking at the knot or mandrel. Faster rate the line tends to break away from the knot or mandrel

Testing mono/Copolymer lines strength is alway related to diameter not labeled strength. Line with the same diameter varied very little between premium mfr’s, tested wet or dry.

Elongation varies more then break strength and knot strength dependent on not flattening the line tying the knot.

Fluorocarbon line varies between mfr’s with Seaguar and Sunline being very consistent breaking close to labeled strength and same diameter, Sunline Shooter FC having slightly higher knot strength, close to 80% vs 75% for all other types using Palomar, Trilene, Improved clinch and SD jam knots. Palomar having widest variances if not tied carefully or twisting the loop when tightening.

I didn’t test braid because rarely used it other then 65# Fins PRC as filler line tuna fishing and straight without leader at the Delta and Clear Lake heavy cover presentations. 

I didn’t keep the data because it was for my information choosing line and knots.

PS, the strongest FC line tested per diameter was Toray Bass Hard (Blue) $35/85 yards in 2015, Shooter was $35/300 meters.

You da man !!! Palomar is it. And they said braid stinks with toothy critters.

They'll bite right through braid, but they ain't biting through those A-Rig wires.

Maybe I've been lucky but the ones I've caught only had the bait in the lips and couldn't break the line. But they could bite your fingers.

That thing is a friggin monster dude. 
 

That one was 43", but my goodness it had some girth. Between egg development and feeding on huge schools of gizzard shad, some of the females I caught last fall were absolutely obese.

Back On Topic: I was throwing that A-Rig on either 50# 832, or 40# Fins Infinity, regular palomar knot, drags cranked down tight. Zero issues. The palomar has always been a solid knot for me with every type of braid I've tried. It's a simple knot that has consistently proven to be plenty strong. Both those braids have been very good for me as well.

I've always used a Palomar and have had no issues even when I don't glue it. I really only glue it to keep the tag end from fraying.
