If we're getting into what a good setup would be once beyond this stage, Diamond Archery makes a Infinite Edge that goes from something like 8 lbs all the way up to I think 60 lbs. I actually bought a Diamond Nuclear Ice (great starter bow) that my son outgrew the draw length capability of, so I went to the Infinite Edge. It's an impressive little beast. If I could have gotten it to my draw length I probably would have kept it. Caution! It is not inexpensive.
Here's the new model of the Infinite Edge. Don't look at the price!! I'm one of those dads who just goes all in.
