I use the Gregory Baltoro currently, I love the extra support it gives. A REI employee told me I'm spoiled with support, he said I will have trouble moving to an ultralight pack because nothing will match in comfort. I've been looking at ULA and Z packs. I was wondering what ultralight pack has the thickest padding, best suspension and over all best support. I'd be ok with a slightly heavier pack if it means added comfort. My baltoro is about 5 pounds empty. I'm looking to drop to at least 3 pounds empty. I like ULA but I have no way to try one on, so I don't know how it compares. Any suggestions?
