Is it legal to put a finger grip in a weight hole? I use that hole as a finger hole to flatten out the shot to cover a 10 pin. Due to the position of the weight hole, the oil line rolls across between the finger holes and the thumb hole. If it is legal, not sure how the grip weight would affect the normal roll?

Holes or indentations for gripping purposes shall not exceed five and shall be limited to one
for each finger and one for the thumb, all for the same hand. The player is not required to
use all the holes in any specific delivery, but they must be able to demonstrate, with the
same hand, that each hole can be used simultaneously for gripping purposes. Any hole that
cannot be reasonably shown to be used with a single hand would be classified as a balance

hole.

You would have to figure the static weight off of the holes you are using for delivery... If the static weights are illegal then you can not use that hole for delivery..

just like you can't flip the ball around and throw it with no thumb if how the ball in your hand will put the statics illegal

check out the usbc equipment specs page 9..

see below.. this may come into play..

Note: the ball must be in specification for balance and hole requirements as the ball rests in the bowler’s hand. A

ball may be in specification if oriented one particular way but not another. Compare Figures 11 and 14

Great info. Never ran into that situation. Never even thought about it.
