Donnie, if you're already educated about bows disregard this. If not bows aren't like guns. You have get measured to buy the right size (draw length) and lbs for each person. A bow needs to fit the shooter. Arrows need to fit the bow too. If you know all this sorry for the message. If not get with a real bow hunter or a real archery pro shop first. I've seen a bunch of guys buy a "bow" at Wally Mart and go out and wound deer because they really didn't know any better. Gives a bad name to bow hunting. Bow hunting is the best!
Good Luck!
