Here's a paste from another thread I responded to:
I've shot the Outback, Liberty, and Justice. I bought the Liberty. The Outback is a very nice bow. Quiet, smooth, and very low recoil and vibration. I disliked the absence of a valley. The one I shot was a 70#er, but the shop had the limb bolts backed out. I prefer 65% let off, and expect it wouldn't be pretty on this bow. I chose the Liberty because of the longer ATA, and I felt less vibration at the shot than the Justice. Recoil was nil on both, actually all three, bows. I also prefer a lighter weight bow. The Justice stacked arrows at 30 yds no problem. I just liked the way the Liberty drew and shot better, for me. If you like the Liberty better than the Justice, I guess the extra money is well spent. BTW, here the Outback is the same price as the Liberty at one shop, and more at another.
