Good luck Man. Shoulder injuries are tough. Took my Dad out of the compound game in his 50's......he never recovered and had to crossbow.
The only good thing was he absolutely slayed big bucks with the crossbow. Took like the 4 best deer of his life with that thing. Everyone of them over 180 pounds dressed with some nice racks.
The nice thing too was, he was iffy with the compound, and had some tough tracking days near the end.....he didn't want to give up. Finally he was letting down the bow one time and he actually torqued the bow so much he took it off the wheels. That was it for him.
When he picked up the Crossbow, if he called me to help, I knew there was a deer on the ground and it would be a short tracking job. It worked out a lot better for everyone in the end. He didn't wound one deer with that thing. Every shot was a smoke show.
