Fireline is excellent as far as abrasion resistance goes... but it's thicker than most other braids (the original fireline fused). The Sufix 832 has this new Gore tech strand in it, same stuff used for Vascular surgery, Bullet proof vests etc... apparently claim that the abrasion resistance is good. Casts well too. I hope it's as good as they say it is, I've spenty a small fortune in spooling all my spinning reels with it!
