Joe,
Isn't surgery fun, just when under on the 2/19. Seriously, forget the light bow, get a box of Altus, latex Stretch Bands ($15.00). There are three in the box, with different resistence ratings. Then ask the Doc for a referral to a physical therapist who can set you up on a workout routine from light on up the scale until you are back shooting what you want. It will take 4-6 months is my guess. Then check with him twice a month or less to make sure everything is going according to the plan. Good Luck.
