Yeah, I'm just thinking of the way they affect the guitar's (acoustic) tone and sustain. Performance-wise, I'm sure the Floyd delivers the goods. If you like that sort of thing. 
i was talking about the tone, too. Sometimes the bent steel saddle strat-style trems can sound a wee bit... wimpy, for want of a better word, if you're playing heavier stuff.
They sound awesome for more vintage tones, though, I'm not slagging them off or anything. There's an awesome sparkle off those strat-style trems. :)
perfomance-wise- yeah a (quality) floyd trem is just awesome. :lol:
