[blue]I have three guitars with Floyd Rose, but one of them are a crap "under lisence by floyd rose patents". This is my Charvel's bridge, have bad stuff. In my guitars the best FR is in the Jackson, but in the Robin keeps the tuning ok too. My robin FR is equipped now with Tuna in 6ª string.
I uses also Tune-o-matic bridges for change easily for tune, in 2 Gibson Explorer.
Floyd Rose has a contra: change the tune. Isn't fast and easy for do it, like in a tune o matic bridge. In tune o matic, is: i want tune it in C#, and is tune in C# very fast. With FR is a bit more complicate. But you can do it in a longer time. Another contra is intonation adjust, isn't as easy like in regular bridges, where you can operate with a screwdriver, and bridge adjust, shall be paralell to the body top. In regular bridges (tune o matic not needs special works here, and strat bridges is very easy the correction) not need special cares. another contra is, u plays a E in 6ª string (for example) and u plays a D note in 22 fret at first string, and bend it
then, 6ª string lose down tune, cos with a bending, u moves all the bridge, in regular bridges (Specially type Gibson) you haven't this problem.
The pro is how keeps the tune, i does sometimes work hard to FR, and always ok.
