There's a post in the elk hunting thread that has the whole story. Honestly for most of the hunting we did a pack was not required. The road system in the Black Hills is wild. We found it difficult to get away from a road. It was a lot of short hikes to glassing spots for most of the time we were there. A good friend of mine who now lives in Nevada and guides elk hunters in the steep country came along and Several times when we were planning longer treks he had me leave my pack at the pickup or whatever we were using as a base point and just roll with the rifle and a few essentials. He was in better shape than me and could move through rough terrain and dead fall way faster, he said if we need it he'd go back for it. It was a good call on his part Several times when we were making adjustments on the fly the pack would have hurt me.
I knew it wasn't going to be a back country hunt as we were staying in a hotel every night but I didn't expect it to be like it was. Having said all that the afternoon I killed my bull I'm glad I had the pack for that particular situation and we did end up packing him out about a mile . For what we did the pack worked good. The Just One is pretty versatile in my opinion and for most of the hunting I do out here on the prairies it will work great. If I was going on a true back country hunt I probably would want something else. But the Eberle would also work. I still really love the the gun scabbard part of it.
For what it's worth my buddy that guides that I mentioned had a Kuiu, my other buddy that was a long bought the same pack as me. The 3 of us packed out the head, hide, and all the meat in 1 trip.
