Okay now. I think most of us agree that Fareri is crap, Rusty is also(IMO) crap. Gambale is a genius, he was the founder of the technique, as mentioned. He sweeps like a complete maniac, but he doesn`t really do any complicated, and most of them are the same. Angelo plays some of the most cleanest and fastest guitar on earth. It`s simply mindblowing. I think it`s in the intro to "No Boundaries", it`s sweeping all the way, clen as hell. Astonishing. But i can`t bear to listen to it more than about 10 minutes though. Also, i think that Romeo beats them all, since he does not sweep the arpeggios, he actually taps them combined with string skipping to do the whole arpeggios. Then it becomes TOTALLY clean, and the need for the sweeping is therefore(as i see it in most cases) almost superfluous...
