seven
I broke and ran 7 on a Gold Crown I playing a race to 7 for $10 against a B player that was getting the 7+8 balls called. I won the coin toss and it was over in about 25 minutes.That was 2 years ago. I tried to keep going to see how many I could do, but thought about it and broke them bad, breakung dry.
I broke and ran 8 in 8 ball on a Valley 7 foot. Then the guy quit me.
This was when I was playing a lot more 2 years ago, running out was almost unconscious. It slips away if you dont compete often, at least it did for me a little.
