One of these, right here:
My Palisade is making it hard to cut down on weight, and 50 pounds is murdering my poor feet, knees, and ankles. that's 50 pounds with only 1 liter of water, so when I need to camel up and wind up carrying 4 liters, I nearly brush 60. The Baltoro is smaller, and only weighs 5 pounds, 9 oz. vs. my Palisades 7.5 pounds.
I'm also eying the Granite Gear Vapor Trail, and maybe one of those Gregory Z 65s. I'll be off until monday, and then back to tearing it up.
