While I am not worried about damaging my actual cue with breaking, I want my tips to be setup for playing not breaking. I use a house cue or my break cue, depending on how lazy I am :smile: most of the time. No need to have a tip pop off or get out of shape when you don't need to. Same reason I don't smoke and drive with a seatbelt, why take extra chances when it takes almost no effort to be safer?
I am thinking that a break shot, as long as you are not killing it, is hit no harder than you would hit the CB if you were playing 9 ball and were hitting a force follow that you intend to go 3 rails. I have never had a tip pop off, ever, while playing. I could be wrong, but is not the same glue applied to a a break tip as a regular tip?
