Also, back tension releases don't conform to a lot of positions you have to shoot from in a tree stand. And in a hunting situation, you definitely don't want to use any type of "surprise" release. For paper or 3D those are great. They make you learn how to hold on target firmly but in a hunting situation, positions vary as well as animal placement so you may have to hold at draw for an extended time. To make it simple, tension releases just suck for hunting.
