I have small hands and fingers so I stick with gauge 9's, D'Addario EXL120 to be more specific.

I tried D'Addario gauge 10's and liked them for my rhythms, but I feel more comfortable with 9's because they're easier for me to bend.

I haven't broken a string in years either. Maybe it's because I change my strings when they start sounding dull instead of waiting until one breaks, which is what I used to do.
