Sorry Einstein but the proprietor does have the first say. But it will not affect scoring conditions. You said it would. What about that do you not get? It could cause damage to the lanes equipment, such as if a piece broke off and got into a pinsetter or ball return. I don't think that would affect your scores. This whole thread comes down to a bowler who in his mind thought it was necessary to enforce the rules and tell the guy to get a new ball. He is one of many who bowl that get a little to caught up in things that really don't affect the league he was bowling in. The guy will not score better with a cracked ball, in fact it is more than likely he will score worse which would have an advantage to the one who started this thread. So back off your wise-azz position and relax.
