In my experiences, nanofil is complete garbage. It casts very good, probably better than any line out there. However, I have tried it two or three times now, and all have resulted in me unspooling the reels and throwing it in the trash. I don't have problems with knots, but the line will just randomly snap and break, anywhere from right above the lure to several feet above. I have lost multiple fish after the hook set. I think if you look at the line wrong it will break! I have even taken a lot of line off and retied. Still breaks. I will no longer be using this product. Way too expensive and my use of f bombs have increased dramatically when fishing with this line. Extremely frustrating to lose fish because that crap breaks. Going to be sticking with power pro and will be giving super slick a try. The end.
