I take exception to your last sentance. Last week we had the chance to load 137 lbs in the Kifaru UL 5200, Osprey Crescent 70, KUIU and a couple Mystery Ranch. The Kifaru was heads and shoulders above them all and this opinion was a concensus from people that owned the KUIU, MR's and Osprey.
Sorry to post this again, I guess Ed missed it.
Ed, how far and how steep up and down did you haul that weight in those packs and what MR's were you using?
How? was the K-UL head and shoulders above them?
