Nothing feels beter to play than a freshly set up, repaired guitar. I spent ages a while back really sorting out my jackson, I even did the friggin intonation which I found difficult, but it plays so nice now.
The only prob I have with floyd rose is its not easy to detune / retune (i.e. metallica is in E to e tuning, children of bodom is in D to d, all strings down a full step), so when i wanna go play somethig that is in the differant tuning, I have to spend ages detuning. So another gutiar would be great for the detuned stuff, I can put on slightly heavier (.10) gauge strings on is aswell to retain some grunt in the tone.
