I use a thumb ring. I made mine out of PVC, the really thick walled stuff. I am right handed and right eye dominate, so I shoot left handed. I use a right handed bow. The interesting thing about thumb rings is that the bow blocks the vision in one eye when you shoot. If you shoot left handed, the bow will block the vision in your left eye. I was able to get pretty decent accuracy pretty quick, my main problem was how weak my left side was compared to my right. I have managed to work up to 40#, when I started 29# would kick my butt. Bill
