What # line did you try FZ1, I tried 15# and I had problems with knots and strength, but the 20# line was very abrasive resistant and very strong line, good for memory. The Pline 100% Fluoro was good and cheap but memory problems with second outing.
As far as strenght and memory Tatsu was better. You know the story with cost. I'm still trying other Fluorocarbon lines. If I'm going to 20# line its probably going to be Tatsu. I tried HALO to and abrasion resistance is good

Just saw this. I tried the 20 Tatsu. 15# P line is stronger than the 20 Tatsu. Use backing line to keep your line use to a minimum. I use braid backing and just put enough for my longest cast + 25' for reties. I change the p Line out about every 3 trips. The P line has more memory but is much stronger.

Awesome awesome line! I have the 15# and it is the best I have ever fished with. I use to fish strictly P-line. Not even a comparison.

Line will last over a year if you take care of it. Spending $50 for something I can use on 3 reels for that long is pretty cheap compared to the other amount of [censored]/plastics/ etc... that I buy and never use is worth every penny.
