i agree with adding springs to the trem, however i would also go about stretching the strings when you first put them in. put them in and tune them as close as you possibly can. then pinch the string and pull up, starting at the nut and run down to the bridge. then retune and repeat the process on the 3rd, 5th, and 7th fret. good luck man, floating trems do tend to hurt people's feelings
