Great tip. I'll play the ghost semi pro where if I don't have a shot on the next ball I'll take BIH. Or just play straight up pro. We'll see how it goes in my next practice session.I'll maintain that I think you play too strong to play the normal ghost. Don't worry about the 7-0 and just switch it up to 'pro' ghost.
It's basically no BIH after break, and a foul is a loss. It's really the only way the 9b ghost is much of a challenge. ...and if nothing else it provides you with a real world measure on how you'd put racks together against a real opponent.
When I do play 10b ghost, I do so with my own 'semi-pro' rules. If I have an open shot on the 1 then I won't use the BIH. I usually lose but that's due to very difficult shape to the 2, and my weak assed break....lol
Cheers!
