10-15 # packs only for day trips and only w/ a short 7mm rope and minimal anchors. I could imagine hut to hut in the Alps on some routes, travelling w/ a sub 20# pack--- or maybe the 10th Mtn. hut system in Colo. if not bringing in a lot of libations(much peer pressure to bring more, not less). Most of my trips are self-supported but that has a lot to do w/ the relative lack of hut oriented backcountry ski opportunities in the Cascades and Sierra.
How about a gear list, Joshua?
I'm not yet sold on the Helix for anything other than real light duty apps. Of course, if we really wanted to shave weight and multi-task, we would have Whippets on our poles and forego the ice ax, altogether, as well as severely crevassed glacier travel and higher angle couloir approaches.
