prs trem or floyd rose

The only trick I did with my FR equipped guitar was top pull-off G string , dive bomb all the way down, then touch a harmonic at the 4th or 5th fret while picking up the bar and raising the pitch all the way up ( sometimes picking the guitar by the bar and shaking it ) . I did that a lot , and it still stayed in tune... I think that says a lot about tuning stability .
