Your findings in regards to noise interest me. My business partner shoots an '06 Tribute and I shoot a Guardian. We have both shot side by side with guys shooting Switchback's, XT's, and Drenalin's. I have always noticed that our bows are every bit as quiet as the Mathews bows, and sometimes more quiet, especially in regards to the Guardian. I shot the Drenalin quite a bit before going with the Guardian. I really wanted to stick with Mathews because I had shot their bows for so long, but I really felt that the Guardian fit the bill better, as far as what I look for in a bow. I'm with GMMAT on this, I would like to know the specifics of both yours, and your Dad's set ups. Not to start an arguement, but to maybe see what the cause is. I have been around quite a few '07 Tributes as welll, and I don't see any reason why your bow shouldn't be as quiet as anything else out there. You have a great bow.
