I'm currently in the process of ordering a custom Anvil at Mike's. But I have to say I tested many break cues, including Sledgehammer, BK2, X-breaker... I have to admit that I hit the balls with more precision with a BK2 because of the taper. But I generated most power in the Mezz PBII with DI shaft. I remember much to Charlie Bryant's own breaks, I generated that much power at one point that the cue ball made a vertical (straight upwards) leap of about 6 (!!!) feet. It landed, bounced a bit until it hopped off the table. Anyways just saying, that I achieved my most powerful break ever with that cue, you have to be willing to settle with a shorter length break cue though.
