I bought a spool of Vanish 14lb a while back, I was carefull with my knots & all, still didn't have good results... I wouldn't use it again, except maybe fly fishing for trout.

I've heard better things about the Stren Fluoro, my buddy was using 17lb this year on his spey rod for silvers, he said he had to go up to 17lb to get the breaking strength he wanted... if they can't see it, they can't see it, right? So then it just comes down to how well you can handle it... 17lb is still pretty stiff...
