You mean YOU don't know how you do it. I do, and Iv'e never even seen you break.
What causes the cueball to go up in the air on a break is the cueball is airborne when it hits the one ball. On your 'home' table, you have the jump distance down pat. But when in another room, with different cloth, or different cueball, the cb doesn't jump the same. So you can't duplicate it. All you have to do is have the cuestick off-level when you break. In the other room you mentioned, just jack up slightly more than you normaly do, and it will give you the same effect.
