I made the switch this year to one, groups improved big time. I could never find a solid anchor with my wrist release, after adjusting a little bit my anchor is now rock solid with the thumb. I did notice I shot better with 3 fingers rather than all 4. I still draw with all 4, but pull my pinky back before going to anchor. I am feeling it allows a more natural angle on the release with my gorilla hands, groups improved more for me doing that as well. I keep trying my wrist release every now and again, and keep putting it back away after 2-3 shots with it. And shoot thumb down for sure.
