My best advise to you is contact Eastmans bowhunting journal. Look them up on the web at www.eastmans.com I needed the same advise as you did last year. I am a longtime Eastmans hunting & bowhunting journal subscriber. I called eastmans & they mailed me a old issue free of charge.
Cameron Hanes had a GREAT article in that old issue that answered all of my questions.

good luck,
