I'm a lot more familiar with the Barney's, but I'm getting there with the Stone Glacier. The size of the Terminus and and lack of pockets did take some getting used to. By the end of this hunt, it was pretty quick to load/unload and get everything dialed in.
I've packed much heavier with the Barney's, so I don't have a direct comparison weight wise, but I'm quite impressed with the terminus for load carrying. I have done training hikes with 85lbs, and really liked how it packed. I'm guessing that the meat/spike camp was probably in that neighborhood or a little more, but of course never weighed it. I do find that it is more sensitive to how it is loaded than the external frames, but it doesn't take much to figure out.
If you are in Anchorage and want to load it up and pack it around for a bit, you are certainly welcome. Nothing beats seeing stuff first hand.
