RE: hind sight users
I used the hind sight about 2 years ago. It will help you form a lot. It forces you to hold the bow correctly. After I installed it my groups were so tight I was damaging the arrows. As for hunting I do most of my hunting from a tree stand and found when you get your body all twisted trying to get a shot, it is very hard to get the crosshairs to line up. As for spot and Stalk it probably work great. As for durability I never had a problem.
