I just got to read all of the replies to this message. Man, I figured my comment and CBM's would cause some commotion in the Bowtech faithful crowd here. I was referring to recoil mostly, but it did rattle some during the shot when I shot it. Not sure of the timing thing but I couldn't imagine Bowtech would ship a brand new bow way out of whack to cause it. The bow wanted to really jump out of my hand during the shot. I realize that placement of the vibration damping thingy's Bowtech uses can affect this to an extent, but wow!

After shooting it, the Vipertec and the Xtec. I can honestly say, bare bow, he Vipertec had the least vibration and recoil. I didn't shoot the Mathews bows after pulling one back. Not for me.
