You have your priorities right....first, do no harm....you don't want a short-term setback to become a permanent one by pushing too hard, too soon. I don't know if you're a hockey fan or not, but as an Islanders fan I know what that strategy has done to possibly end Rick DiPietro's career as an NHL goalie. So skip this season if you must. But see if a slow and steady work-up to a 35# longbow will get you into the woods this fall. Even an inexpensive selfbow of that weight could "keep you in the game", and that's what it's all about right? Carrying around the heavy mass weight of a crossbow or compound won't do you any good, either, but a feather of a longbow would be no strain at all.
