I have always used Bibler for all my winter mountaineering. I use a Black Diamond Lighthouse when weight matters and it's not going to snow much. I like the single wall interior pole designs of these tents but I did have some issues with the Black Diamond perspiring and getting pretty wet inside. I sent it back and they sent me a new one right away with no questions asked. I am still very happy with the tent. Anyway, I am thinking about getting another bigger Bibler for river trips. Do they do well in really wet environments? The Bombshelter looks pretty sweet!
