I think you have the knowledge inside yourself to make the right decision. You showed that to me by liking a cut on contact head. There are so many good broadheads on the market today and listing a few, Muzzy, InnerLoc, Wasp, Rocky Mountain and so on. With his limited poundage and with that I assume KE...I'd stay away from mechanicals but I'm sure you already know that.....just pick one your secure and confident in and get the boy out and practice with them. Limit him to certain confident yardages and have a great season.
