I'll have to agree with you on that one mate, having spent a lot of time setting the one on my Hot Rod Strat,I can only say that Floyd Rose Trems are a royal P.I.T.A. (excuse my French) to set up so that they work correctly, and even then they are only about 80% effective at staying in tune, you have to really want one to be able to put up with it.
I've only just managed to get the Floyd on my Hot Rod Strat sorted out, boy what a pain, I hope none of the strings on it decide to break.
I do know some tricks to make them easier/quicker to set up though.
