I also use cheap strings because the tremolo bar is not left unused on my guitar. I think I snap a few strings every week. Sometimes daily if I'm really into hitting the tremolo bar

.
I never tried those coated strings but they're way too expensive for tremolo use.
Mayby another question, half off-topic, It'd be stupid if you're on stage doing a kick-ass solo using the whammy bar and then SNAP! Do springs snap less easy when they are brand new and you pull the tremolo up? Maybe change strings 2 or 3 days before gig, so they don't go out of tune and you can still safely "stretch" them out?
