I've had/have a bunch of them, and don't find fault with any. I've had a few of his older bows, and the limb design really didn't seem to differ much, but where I saw the biggest difference was fade to grip size and shape. Seems his grips have become a little smaller and narrower over the years.
I love my Hills, and Craig is an awesome individual to work with. Patient as an oyster.
I've sold a few (a couple I'd like to have back), but only to raise cash, or because I needed or wanted a different weight or lengths. Never through dissatisfaction.
You certainly can't beat his turn around time. You won't be disappointed.
