I agree that not all manufacturers pound tests are not the same. I know that lines with more stretch seem to break at a higher poundage. I look at the diameter more often than the pound test. If you look at lines like Yo-Zuri Hybrid they have a higher diameter than a trilene XL or even Vanish. Diamater is what the fish see, not the number on the box.

Yozuri Hybrid is a weird one. Some of it's test# line diameter is smaller and some of it is larger. I forget which of which. Unlike Trilene XT, all of it is typically larger diameter.

If one is to use a more acurate gauge of line strength. You have to measure break # against diameter and compare that amongst the lines. For what's reasonably affordable, Yozuri Hybrid and Gamma are my top choice because you can drop down in line test on box label and get the same break as other lines. We all know that line break strenght alone is not a good way to buy. Other performance factors should be consider as well, like how stiff or how supple the line is, anti-abrasion quality, line coil memory, stretch deformity, line visibility or invisibility underwater.

Dietz, 2 years ago I did a Straight pull test for several lines all in the 12 pound test category and every mono and flouro that I tested below or at the 12 pound mark. The powerpro performed the best at around 14-15 pounds. Just for fun I put some year old 8 pound fire line on and it broke at 17 pounds. That is the main reason I use fireline today.

ocf1,

what brand and which line did you test? Could you also elaborate on the method of test as well, thanks.

I know for sure it was trilene XL and XT for mono, maybe one more. I am not positive on everything else though. Gamma was not tested, nor was yo zuri hybrids. For the test I attached the line onto a basketball hoop through the use of key rings. One key ring was on the hoop and one was on a 5 gallon bucket. bungees were added loosely. I then filled the bucket with water until it snapped and weighed the bucket.

Were you experiencing line break at your knot or midway through the line itself?

midway

I wonder if the heavier briad, like 50 lb power pro breaks near 50 pounds. I think I'm gonna test it, I will post my results.

TB- every time I have tested it, it has not... However, it really depends on how you test it. Getting a knot to not(knot) fail is the hardest part...

Be careful, one can hurt themselves testing 50 lb test.. LOL

I like using the old lizard for Carolina rigs.

A little story about 50 pound power pro:
I was trolling for pike one time in a Grand Rapids area lake with a #9 shad rap. I got hung up big time (must have been a log or something) in about 16 feet of water. I was unable to free the lure as I tried tugging on it from every direction. So all I could do was pull on the line.
Well, after trying with bare hands for about 2 seconds, I decided a lure wasn't worth losing some fingers so I used a hand towel to wrap around the line and pull. I pulled and pulled and man, is that line strong! Finally, it gave way and broke what I thought was the line. Wrong. I reeled in and on the end of my steel leader was the split ring that bent open and freed itself from the crankbait. I couldn't friggin believe it!

maybe a test isn't needed for 50 pound power pro. Sounds like it's already been done!
