For those that says, so what! try to run 35 points on the two snooker tables hear in the villages shooting at any colored balls not just reds and black. Course the one at Chula Vista easier cause its only 10 foot and has 2 1/4"balls which makes the pocket bigger. Good luck on the other one that's 12 foot with 2" balls and really small pockets.
