How about a 40# peak weight compound? There have been plenty of archers who have had similar injuries. You might not be shooting 70#s.... but with some PT and rehab you can still shoot a bow.

DryRidge comes and goes over on the technical forum here on hunting.net. Shoot him a PM... he is old as the compound bow and has forgotten more than I'll ever know about them. I know he was hunting last fall rehabbing with a 32# Mathews and killed a couple deer with it.
