floyd rose, it allows you to do more shit and the tunings ok cuz once youve spent the 10, 15 mins tuning it pretty much stays in tune if youve got a solid trem
I don't have one. It is funny to play on a guitar that has one, but I don't feel as if I really need it. IMO it doesn't add anything to my playing. And if i did get a guitar now with a Floyd, I think there is a considerable danger of ending up just whammying away. So so far, no.
