I tried a back tension release on a longbow once, years ago--dang near killed myself!

I've heard of folks with severe arthritus in their fingers using a release aid, but haven't heard of anyone using a loop. It will surely help with any release problems, but for me it would just be one more thing to loose/forget/drop/malfunction, and they aren't allowed in tournaments (I love to shoot 3-D in the off season).
