I used a Floyd Rose equipped Charvel for years and learned a lot of the techniques mentioned above by trial and (lots of) error.
Now i use a Blade RH2 with a standard Strat style trem and locking tuners and it never goes far out of tune. It also avoids the Allen key search, and if a string change is needed, it can be done easily between songs.
If like me you only use your bar to add vibrato to chords, and the occasional dive bomb. You'll probably find it's much less fuss to use a normal bridge. We got Polytune now anyway!
