There is also the issue of your body falling apart with ware and tare after years of shooting hundreds of arrows a day. The muscle may still be there, but the joints and tendons argue with you. a light bow can be shot Hill style as well a heavy bow. Hill did not always use heavy stuff. he had bows as low as 52 pounds to use. If you need an 80lb. bow to get a good release you may find that a lighter bow will fight with you for a while, but in my case you do learn to release better with practice
