Bowling Thumb Straight

Instead of gripping onto the ball with your thumb, it should be as straight as possible.

To get out of this bad habit, this device is excellent for helping you get a better release, with more lift. ALso, if your thumb hole is slightly large, and/or you get sore knuckles, this could help you out!
