So backcountry.com has the Black Diamond Big Wall and Hooped Bivy on sale and I'm considering picking one or the other up, probably in a long.

The site says that they weigh the same but that the big wall is much more compactable. I really like the look of the big wall more than the hooped but it seems strange that it would be so much more expensive. Though if I do buy a long the big wall ends up being only $8 more expensive.

Anyone want to chime in on the pro's and cons of either bivy? I'll be using them for hiking on the cali coast(either with a tarp or without) and probably some mountaineering next year once I can afford the lessons and gear (shasta, lassen, etc).

Or should I say the heck with it and buy a marmot alpinist, saving both weight and money but possibly getting eaten by bugs?
