I am having a problem with loosing the bowling ball during the swing. Can't seem to keep a good grasp. At times, it feels like the thumb slips alot. Causing a gap between the index finger and bowling ball or slip at the pinky finger. Can't get confident on the shot when this happens, unable to maintain consistency. Any suggestions on how to maintain a better or good grasp on the bowling ball during the swing would be greatly appreciated and helpful.
I see a lot of power players bend their pinky finger with the finger nail on the bowling ball. How does this effect the grip and why is it done? Is it painful to do?
Thanks in advance.
