I'm sure it will have a little more vibration, but if I go with a heavy enough arrow to keep my bow shooting the same speed I am shooting now, then I wont experience any more vibration than I am now. The string, limbs, and cables will be moving the same speed. The heavier arrow will take on the extra KE. Either way, the X-force had a SIGNIFICANT amount of more vibration than my Vulcan.....basically like going from practically dead in your hand with a 537 grain arrow (Vulcan) to jumping out your hand (X-Force).
