I stand corrected on my first post for this topic, I stated the switchback xt is longer axle to axle than the outback. I realized this was incorrect shortly after my post but wasn't at home anymore so I couldn't correct my post. The original switchback is 2 inches longer but the xt is the same (or 1/2 shorter I guess). Nonetheless, the outback is not a real forgiving bow. If you are going to buy, do yourself a favor and test shootthese bows with sights on them. That way you can see how good your groups are. Just shooting them instinctively at a target 10 yards away in order to determine the "kick" and vibration is only a part of the equation.
