I'll tell ya what....Vanish is indeed crap. Try Stren's version if youy MUST have flourocarbon line. Heard that people catch more fish on flourocarbon too. Funny, I seem to do just as well as the guys throwing that "invisible" line when I'm using Ultragreen. People probably say they catch more fish than they did last year because they are 1 more year experienced. The year after they'll say that they caught 60% more. Experience counts.....Not leader.... I'll never switch from Max UG. Love the stuff.
