Well I guess I am a fanboy for liking Kifaru for my pack. I have used quite a few of the top tier packs and hauled out animals with many of them. Pack fit is a personal thing and I found that Kifaru fits the sweet spot with its duplex frame and EMR 2 packbag for my needs. Doesn't mean its the best choice for most or even many folks, but I could care less what others are using and wouldn't let affect my decision. I think most find the EMR 2 much to large and bulky for their needs. Don't really care, I know what I need and thats really all that matters.
That said I am eyeing the Paradox Divide pack pretty heavily for my summer hiking/packrafting trips though to save some serious weight over my Duplex/EMR 2 as these trips start out lighter and get only lighter from there.
Sounds like the Stone Glacier could/should be just what you need and if thats the case go for it man. I think you will be happy with your purchase of the Stone Glacier, but heaven forbid there gets some serious fanboys that jump on the SG bandwagon and make you regret your decision.
