Joe,
I'm talking about the frame and overall suspension system, which is where the rubber meets the road. Pack bags are, well, bags...whose differences are largely superfluous.
Not that it matters, but I'm not sure how anyone can't see the uncanny resemblence to Kifaru's Duplex. You can toss the KUIU out since it's carbon flexy/breaky sheet is a not a stay supported platform that you can modify. At least the Storm Glacier's suspension system looks robust. Hopefully I'll be able to swing through Bozeman in a couple of weeks on my way to WY and take a closer look at them. 2.16 lbs. for the frame is very intriguing.
Load lifters on a MR NICE frame??? They're non-existent.
