Why are you perpetuating the myth that the 9 on the snap 3 times in a row could have anything to do with the break cue or for that matter even the breaker? It's from poor racking.
I've made the 9 on the snap 3 times in a row with a house cue. Why? Because the cloth was worn in such a way that it was impossible to get a perfectly tight rack, in particular in the bottom 3 balls.
A local pool hall uses "rack spots" that, when installed correctly, ensure a perfect rack every time. Every ball is frozen. No matter how hard you smack the pack, or from any angle, the 9 barely moves. The only way it goes in is if balls go off a couple rails and happen to knock it in, which is rare enough that you never see it happen 3 times in a row.
Not to mention, in professional tournaments with proper racking, how often do you see the 9 ball move far from the spot, let alone go in 3 times in a row? Or are you trying to tell us that you, and your cue, are better than every professional in the US Open?
By the way, at this year's US Open, they used a Chameleon rack instead of a Sardo, and it (the Chameleon rack) did not do a good job at all. It was so bad, I think I'm gonna start a thread abvout it in the main forum and see what other people thought. Despite that, I didn't see anyone make the 9 three times in a row.
Make no mistake, I am quite sure your J/B cue is awesome. But the paragraph you wrote to hype it hurts your credibility.
