I've decided to take up two handed bowling for the summer to have some fun. I want to drill up a couple balls but am not exactly sure about the rules regarding the static weights. I want to drill the balls with finger holes but no thumb. I will be throwing the ball a la Jason Belmonte (though not near as good haha).
What are the balance rules for a ball drilled with finger holes but no thumb hole?
I found this on bowl.com.
"Any ball used with a two-handed delivery with or without holes or indentations may not have more than 1 ounce difference between any two halves of the ball. "
Does the 1 ounce difference include topweight?
Is the "center span" measured directly between the two finger holes?
The way I understand it all, is that the top, finger, and side weights must all be within 1 ounce of each other and the center span is measured at the middle point between the two finger holes. Correct me if I am wrong.
Thanks

For the sanity of your ball driller and the ability to be remotely versatile with layouts you need to use a thumbhole. It just needs to be covered by your palm while you are throwing the ball.
If you don't use a thumbhole you are EXTREMELY limited as to what you can do with the ball.

just drill the ball to your hand for traditional 3 finger... then bowl with 2 fingers... that way when/if you switch back you can use the ball!

Read the rule again, folks. It plainly says that ANY two handed delivery, no matter how many holes the ball has or the bowler uses, requires a ball that has no more than 1 ounce difference between ANY two halves of the ball. If they mean what they said, that would include top/bottom halves, side halves, finger/thumb halves, and ANY OTHER two halves you can imagine, for example the halves created by a traditional full roller initial (and subsequent flare rings) track. They may mean just the traditional three pairs of halves, but that's not what they said. -- JohnP
