I suggest leeches for the string, and either wiskers, or leeches for the return string and/or buss cable.
I have a drop away rest, and the string served to the buss to operate the rest seems to quiet it down enough. On the return side of the string (1 cam bow) I put another leech near the cam. Big improvement.
Wanna know if it makes a difference? Just pluck the strings like palying a guitar...then put the leeches in.
I don't like wiskers on shooting strings anymore, because the speeds of new bows has the wiskers making a bit of wind noise. The damp vibration well...but to <u>ME</u> they seem to make more noise while the string is in motion.
