From my understanding the bowtechs with the infinity cam and the new freedom cam will allow one to micro-adjust draw length as well as install different modules as needed to match the draw length needed.

I suspect if you can provide more details about the 14 year old, such as current draw length, how much weight he can comfortably pull, etc, you' ll get more definitive answers from the bowtech guys here. I' d also recommend posting this in the tech forum if you don' t get a response, or dropping Bowtech Shooter a pm or email.
