Jeff65 - It's funny you mention that. A friend of mine had a Floyd rose Ibanez back in the 80's and never complained about keeping it in tune. But I've read in various places recently that it is a pain to keep in tune.
I'm sure you are right - personal preference. I can't be any worse than keeping the standard floating bridge of a strat in tune - now that was a PITA! Things are much simpler now that I have it tensioned down against the body of my guitar! If I need to use a whammy bar, I'll probably buy an Ibanez...with a Floyd rose :-).
