K0m4, yes, bulk is certainly an issue. I suppose its all relative. Traditional or suspended, it still requires approximately the same volume of equipment to keep you comfortable in sub zero temp's. You also made a good point about packing snow under you rig but I think that sort of defeats the idea of set-up time. It would certainly work though.
There is also a local site that people can sell their used equipment. I think I will check them out. Mostly deal with hiking, climbing etc equipment.
Titanium Hiker.....you mentioned that your winter kit weighs only 89 oz. That is pretty impressive. Does that include the bags etc or just the hammock. Also, at what temperature are you comfortably able to sleep in.
