supaarcher-----owning a MMMMMMathews,you will definately need all the help you can get
Seariously though-----string leaches or cat whiskers can help in big dividends.Try a good stabilizer as well like the Doinker D2 .
All bows no matter what manufacteur they are, have noise coming from somewhere,vibrations of some sort.The stabilizer and string silencers I mentioned can do wonders for your bow,and for your shooting.
Good luck
