I use 10's on my electric, 11's on my acoustic, and haven't broken a string in ages. I've tried 11's on my electric, but I did notice that it made bending a lot harder, and switched back to 10's, just to give you an idea. Dan's suggestion of wiping the guitar down is a good one, though I hardly ever do it. I do wash my hands though before I play... with Dove.. yes, Dove soap really gets the job done.. ok, ok, I won't start that again! ;)
