This really perplexes me. About a month ago, I tested a Kodiak (36" model). Without any doubt in my mind, it was the quiestest bow I've ever heard. And it wasn't just me. The same judgement came from the other 10 guys that were at the shop at the time. However, it also had a great deal of vibration in the grip, on the shot. Now, this test says the Kodiak was the loudest, yet good enough in other areas to score high in the test! All I can say is, that either there is a lot a variation from bow to bow, or the setups did not include identical vibration control accessories. The results of this test are so far out of line with my experience on this bow, that it leaves a lot of doubt in my mind, as to the value of someones else's opinion of a bow.
