My friend and I are going to a 4-5 day trip from aspen to crested butte, and on to Marble starting on friday. The weather doesn't call for much snow, but we will be camping on it. Honestly, I feel like its a bit of a toss up, and either shelter would do the trick, but curious which ya'll would bring. I've got an msr twin sister which I used on a similar trip in the san juans last year and it was excellent. And then I have a zpacks duplex, which would save me 12oz. The weight savings in nbd, but I am curious about trying to push the duplex into winter conditions. Then again, I can pretty much set up that twin sisters wherever I want and count on bomber protection, given a good stake out.
Any thoughts?
