I'm certainly glad to hear about your son wanting to get into the sport ,good for him .My kid's were 6 when they started shooting a bow ,I started with a small recurve and then they moved up to a BowTech Rascal which you can get down as far as 30lb's which might be a little much for him right now .I'd give hima year with the recurve and then move him up when he's strong enough to draw a small compound .
