I am wondering whether or not this could be a tuning/release issue for the noise. As an example, I talked a young fellow off of his three under release because he was hooking hard with his ring finger just before his release and really throwing the bow out of tiller. His argument was that he would have nothing left to aim with by going split, the change did quiet his bow down considerably. My experience with the 48" mag is that it is softer in the cast than 52" and the 60" Bear recurves and requires one spine less in aluminum arrows.
