Well, never, can't remember ever breaking a string.
I play with fingers and a pic, for a few years in the 90's exclusively pic. Played some quite heavy music.
I did break a few while setting up a fretless a few years ago, but I was using old strings and took them up to tension and down again many , many times while shaving the board down and fiddling with the truss/saddles.
I can honestly say that I've never broken a string gigging, rehearsing, recording or noodling around at home.
