My son is 8 and we went with the Diamond bow. The smaller one is from 15-30 lbs and the the other is from 31-60 lbs. He is pulling 35 lbs now and shooting good. If you have to go with the smaller bow you can upgrade for like $50 or something. My nephew has the smaller one and he is left handed, they are nice kids bows. Alot of the women at the bow shop are shooting them too.
