Jangus,
On my pike traps I tied 35# tyger wire, which was coated, and it ties like 40lb flouro leader. just use a couple drops of superglue on the knot at both ends. I will say that I have noticed more flags, not necessarily more hook-ups with flouro, could have been the day, I like to think it was because that flouro disappears in the water. All I fish for is pike, and didn't have a cut line last year. 50lb flouro, still use the superglue. and tie 4 or 5 extra leaders. A big fish will cut it up, but like I said, I haven't had one cut off. Good Luck.
