bigfish -- Bushman gave you a couple of good links in your other post. For a beginner like yourself, not having any pro shop tools, it would be best to go to a pro shop and ask them to watch you throw a few and locate your PAP for you. They can do a better job of trouble shooting your problem than someone that can't even watch you throw a ball can. A full roller track is one that is between the fingers and the thumb. -- JohnP
