I bit the bullet a while ago and went with a Mchale Inex. It's Kifaru light, Barneys stout, and more comfortable than any other pack I've every used no matter how much weight I've thrown in it. I've used it to haul out my last 5 sheep and I couldn't be happier. I got rid of my Kifaru but liked it and I still have my Barneys. I've watched my hunting partner go back and forth between a Barney's, Kifaru, and Mystery Ranch over the last 9 years but has stuck with the Mystery Ranch for the last three and from what he tells me that's what he'll be using again this year. I have no comment on the Mystery Ranch I've never used one but I seen my buddy so loaded down with his that he looked like a dung beetle from a distance and he packed that load a long way.... I think if you pick one of those 3 or take the plunge on a Mchale you'd be happy.
