MJnevetS -- I think the lack of responses to your request is because what you have asked for doesn't exist, not because we are hesitant to help you. I would suggest that you expand your topic to cover bowling safety in general, including proper fit of the ball to avoid damage to the fingers and thumb, how to properly pick up a ball to avoid being hit by another ball being returned, and proper lifting techniques in general to avoid back injury. To obtain your information, schedule an interview with either the manager or the pro shop manager of your local center. I'm sure they will be more than willing to help you out. Good bowling -- JohnP
