It's fun........and very convenient to do yourself. Tear up some feathers or vanes just grab the jig and fix em up.
You could really go off the deep end like me with a bag full of wild turkey primaries, sand paper, 2 feather choppers, and not a clue what you are doing and try and make your own![:-]
In any event I also recommend the Bitz. Get all the clamps and nock receivers to match........ya only live once.
