Years before break cues became popular, I broke with my playing cue or a house cue all the time, mostly the playing cue. Custom Joss East {tells you how long ago this was} with a steel joint, ivory ferrules, and Champion tips. I have never broke the balls better than I did with the Joss, including when I had a pre-Sledgehammer Gulyassy. Since breaking with the Joss I've used various cues as break cues including a Mali, a '70s Adam, a Joss Boss, Meucci, the Gulyassy, and several others. Other than the Boss and the Gulyassy I haven't owned a cue specifically for breaking. While special made cues may help, I think that it may be technique more than the cue itself. When 9 ball became the main tournament game in the '80s, I began to change my break like a lot of other people did. I've experimented with the side rail, which doesn't work well for me, and a few others. I've always had more accuracy and control from around the spot and never more so than with that Joss cue. It's one of the two or three cues I sold that I wish I never had.
I'm now giving serious thought to breaking with my Dishaw.
