First off, welcome to the board. Parker makes great bows! I messed with alot of them when we sold them and we always called them po' boy mathews bows. Shot great, the adjustable module was a real convenience for people just starting out and kids as well that needed to be able to grow into their bows. You say he's pullin that weight easy, but you need to make sure that he can pull it comfortably over a long time. No sense in being able to draw 70 pounds real easy for about 3 shots. If he can shoot a 60# bow with no real problems, and the draw length is right, then i would say go with the parker. Just make sure you dont overbow him to begin with.
