Turk I started shooting at 65 pounds and just recently went to 70 and the only reason I went to 70 was because I bought a new bow. I agree with David, you would probably do your self a favor by backing the bow off until you are pulling it easily and then increasing the draw weight. You not only could develop bad habits pulling to much weight, but could hurt your shoulder long term.
