When I first brought my Trykon home (actually I told my wife it followed me home), I noticed a very slight buzz in the string. The bow was still as quiet as my neighbors Switchback, so I didn't give it much thought. Well, a couple of weeks later the Hoyt dealer called me and asked me to bring it in for a fix. He said the Stringshox sometimes separate the string enough to cause some vibration. He tied real small rubber "tarantulas" at theend of both Stringshoxandthat eliminated the sound completely. How many dealers would call you back like that?!
