This might not matter to you but the New modles will be quieter and smoother in my opion. I still have some 1996-99 model High County bows that I shot and they still kill as good as the new ones but are louder and more have hand shock. Its all in what you want. As far as dual cam, like mentioned before they are coming back unless you like the Darton' s CPS (Most under rated bow on the market) system and the Hoyt' s Cam&1/2 (which I have both

).
