I love my horns but I have noticed that many people "rattle" them to much, instead of grinding and twisting them. This realistic grinding can be acomplished very easily and with very good results from a "bag". My favorite sounding bags are the Knight & Hale with their great sounding VTS tines and the new Lohman Dynamite rattler which isn't a bag at all.I think the Lohman is the one Bowhunter57 is trying to desribe, it really does sound great and you don't have to worry about the bag wearing out and tearing.
