Definitely go with some Limbsavers, without a doubt the biggest noise reduction tool you can add to you bow. I think an STS or string tamer type silencer that attaches to the front/rear stabilizer bushing would be the next most productive along with some type of stabilizer. Then your string/cable leeches, & cable guard if you really want to get carried away.
