RE: bow ideas
Another good choice is the Reflex line of bows by Hoyt. They have the Cam and a Half system and are very good performers for the money. Additionally the cams are draw length adjustable over I believe a 2 or 3" range.
I would be wary about buying a bow with non adjustable cams in the event that you do hit a growth spurt, or find that the draw you have been shooting for the last couple of years is either too long or too short.
