I've been working on a new (to me) break. It's working way better than the old break. The key with the break I'm working on is that the 2 is always racked in the back here, it's some tournament/league rule thing. Wing ball goes, 1B can go in side, or preferably stays as a side duck. 2 ball goes up by the corners at the head end. Balls spread out well. One caveat, make sure the CB stays in the middle, because if it scratches the opponent will run out.
CB on head string, between 1st and 2nd diamond, closer to middle (2nd) diamond on longer tables, centered between 1 and 2 on 7'. Hit medium soft with the stroke that will instantly kill the CB. About center ball, maybe 1/8" below center with just a slight suggestion of inside or outside depending on the table. Outside usually gets the action I'm looking for.
It is crazy the difference a good break makes, if it goes haywire there's always the push option, but it goes haywire a lot less often with some experimentation.
