To protect bowling’s future:
• USBC is eliminating balance holes
• Setting a new specification for oil absorption
• The overall result will slightly limit hook potential
USBC research shows these changes will:
• Slow oil pattern transition
• Cause bowlers to move less
• Keep the same scoring pace with lower oil volume
Why did USBC eliminate the balance hole?
Balance holes were originally intended to correct a ball that was drilled outside of our static weight tolerances. However, in recent years, balance holes have become a tool for pro shop professionals to manipulate the balls. Our studies determined the balance hole can greatly increase the Differential RG to strengthen the reaction of the equipment beyond the ball’s original design intent.
Please help to check my understanding.
1. Differential RG = Total differential?
2. Balls with high total diff will hook more (and carry away more oil) . Why? Because of larger track flare or something else. What if a high diff core inside plastic or urethane? Obviously, it hooks less and the track flare is minimal. Will it carry away same amount of oil as the same core with reactive resin coverstock?
For quite a while, coefficient of friction has been the ultimate, determining factor in the bowlers ability to break down oil patterns. To prove that, the Strohs teams of old, would select bowlers who basically rolled the ball the same. They were all full rollers, same speed, and had the same trajectory. They were all very accurate, burning a slot into the oil pattern was an art they had mastered.
That was long before "oil suckers" were in existence.
Now, the same "burning a shot" exists, but this mainly concerns high rev / high speed players. Because of the amount of flare they create, coupled with the oil absorption rate of the equipment, they will create a much wider path in the pattern. Think of if as a sharp V shape.
When Stroh's broke down the pattern, everyone on the lane could still play. Stroh's won, simply, they were more accurate. In today's game, when a no thumb bowler breaks down the pattern? Well, you had better be EJ Tackett to compete.
So, the rule is earmarked toward high rev players. If they can be shut down, bowlers with lesser physical ability can stay on the lane, in their comfort zone, a lot longer.
Does diff factor into the equation? It would be pointless to argue that it doesn't.
We know and understand the intent of the rule. But, there are a whole bunch of 3 game a week bowling participants who have an extra hole in their ball. A lot of them are going to say: "Why the hell did you put that hole in my ball anyway!"
