I have one roll on right now. I had to replace it once (company was good about it) because it was the old "wide-spool" version which birdnested and frayed. The new roll doesn't nest, but it has frayed in the last 6 feet (thankfully not deeper). I have cut that back and am now keen to see if the problem comes back. It is a better knot tying line and doesn't kink as much, but if the fraying continues, then I would pass. TBD I guess.
