Deer-Slayer, i reconize something in your problem there. My youngerst son is 13 to and something like 6 feet allready. I had him set-up with a pse nova 3 years ago and for this season it was wayyyyyyy to short for him to. The poundage was not even the biggerst problem. I took the cams from my old pse and put them in his nova. So now he can draw it a bit futher, and i decided to wait a little longer with buying a new bow for him.
For you, i would like to warn you to be carefull on what you going to do.
It sounds like you need another bow anyway but i dont think you are ready growing.
So maybe its better to wait a little with buying a new one and choose for a second hand first.
I believe there was allready help comming your way in this.

Good luck on your new bow!
