That 30-inch drawlength is definately WAY too long for you, bud. Even if you become strong enough to pull that draw weight, it'll be nearly impossible for you to shoot well since your anchor point will be 2-6 inches infront of the let-off zone. At full draw, you'll still be holding close to 45lbs. Do this....stand facing a wall and spread your arms apart as wide as they'll go. Don't strain or stretch, just let them extend to their natural extension. Then have someone measure the distance between your middle fingertips. Take this measurement and devide it by 2.5 and this will give you your correct drawlength. For example....my "wingspan" is 73 inches. 73 devided by 2.5 is 29.2 inches. My bow is set up at 29 inches but I also use a D-loop which adds about .2 inches.

For you to properly shoot your bows' 30 inch drawlength, your wingspan would have to be 75 inches. I'll bet your correct drawlength is closer to 24-26 inches.
