Adapters work great. I recommend determining your desired point weight, buying the adapter that, coupled with your broadheads, will duplicate that weight. Then dedicate a 1/2 dozen carbons for broadheads (or at least mark them so you can match the BH with the arrow). Clean the adapter and BH, and mix up some 2 hour epoxy. Take your time gluing and spinning, turning, spinning, etc, etc until everything spins great, then let the epoxy set. You'll have a matched set of BH's that wont pull off in targets. Practice then sharpen those puppies and put some meat in the freezer!
