Roger,
I know Ron likes the cat whiskers cause my bow had them on them when he sent it too me. It may be my ears, but I like them dead animals on my string better than rubber ! I use two large beaver or muskrat fur silencers and they seem to work well. No " Twang " , at all. The only bad thing about animal is they do look pretty sad in the rain and can catch burrs when hunting in brush. The cat whiskers are better in those two areas. I remember last year during our hunts we would sit in the stand and kill time by picking the beggar lice out of our fur silencers.
