RC, they are really noisy in high winds, the cuben fiber rattles pretty loudly. We were kept up by a friends, one night this past Oct. with a front moving in. You also need to add the weight of the stakes and a ground sheet of some kind. And it supposes trekking pole use. At 64" it would also need an extension on most trekking poles. Either that, or you need to factor in the weight of a heavy knife or saw to fabricate one. Something not always easily accomplished as you get up to treeline. For me, I'd have to have the mosquito netting, too. Looks like a great, roomy shelter, just a little pricey for me when I factor in the add ons. By the time Ti stakes, netting, and floor + tax is added, it's going north of 800.
I'd look around and weigh the options before pulling the trigger, but that's just me and my particular tastes and needs.
