Well, we have had our Demo Switchback in the shop for almost a week before I got a chance to set it up and shoot it. Now I have sold lots of Outbacks and they are great bows. However, the Switchback is in a league by itself. I shot this bow at 69# according to my scale with only a loop on it. No sight, no stabilizer and it did not have the brass dampners in it, just the aluminum dampners. We shot my hunting arrow through it which is 413 grains Axis 400 arrow. When fired, the bow absolutely does not move, no vibration, no noise, period. If your curious to the speed....how about a smoking 285fps with a 413gr arrow at 29" draw? Now I'm not hyping Mathews because I in fact shoot a Hoyt, but this Switchback is amazing.
