I had 2 rigs set up with the 2# test Nanofil for crappie & perch fishing. The line performed great as far as casting goes, but I had a terrible time with knots! Lost many jigs on hooksets, no matter how careful & gentle I was! Tried a fluoro leader too, but it didn't fare any better. Now I've been using 2# & 4# test mono for panfishing for more years than I care to think about, so I am familiar with using UL lines & rigs. However this particular line was a big disappointment for me, due to knot breakage, regardless of how careful I tied them. Maybe the 4# test would fair better, but I'll stick with 2 mono rigs (2# & 4#) and one with Fireline (4# test). These rigs have never failed me.
