I haven't seen fusion around here in a while. I used to use it, but it got bushy like sisal baler twine, and all that friction on the guides made for poor casting. I never had problems with break offs, but it did seem to bleach out and fray with little use. I also gave power pro a try, and disliked it for several reasons (we will save that for another post). I have finally settled on Spiderwire Stealth, I love it, and I find more uses for it every year. Stealth handles like a dream, stays round, never digs in, never looses its coating, and lasts for years.
My final verdict:
Fusion sucks
stealth rules
