RE: brush buttons
I quit using brush buttons many years ago. The last time I bought any was somewhere in the early 70' s. There were two types that I remember. One was dark brown and pretty firm. Those did make the bow louder, making an audible sound when they hit the bow on the shot. The other type was flesh colored and soft. They helped cushion the string and kept it from slapping the limb, and that made the bow shoot quieter, but they were so soft they' d break after a couple hundred shots. I just never bought any more after I ran out of them. Can' t say I' ve missed ' em either.
