Once again Brother Chuck, happy 51st, I turned 51 in Novemeber 2004 so I know the aches and pains that are just starting![8D]
BTW I can't tell if you have a wrist strap or not, but your groups will really tighten up if you get a wrist strap and shoot open handed. I didn't think it would make a difference until I bought a new bow and it came with a wrist strap and I tried it, by shooting with an open hand it stops you from torqueing the bow when you shoot, as with Christ where you must have faith, you must also have faith in the wrist strap in the fact that the bow will not fly out of your hand when you shoot.
