Noel, I pretty much went through this discussion a while ago on here. I haven't had time to work on drawing heavy bows but I do want to get back into it eventually. There's a guy on here, Marlon Torrez, who goes by heavybows who is ridiculously strong and still struggles to break the world record. Check him out on his youtube channel and you'll see what I mean. I'm not saying that you shouldn't try but take your time. You're mind will push you past your body's limits and that's what causes injury. Listen to your body and good luck.
