I have tried 4 kinds of fluor, red lable,invizx,burkley 100 % and p-line and I have lost too many fish on the hook set and I will never use again. Maybe when they improve the knot strength and cost. I tried 10 # and 15 #. Fluor might work if you change it a lot but that cost to much. I only put on 50 yrds. at a time and I thing you need to respool every other time out, which would make it to expensive. I use 12# sunline mono. Its cheep and I change it about every 5th time out and I use 15# cxx copolymer for my jig fishing and I change it every 4th time out, its VERY STRONG ! and does not break.
