I wanted to get a single walled tent that I could slug up Shasta or Rainier. I looked at some Biblers, but they were relatively more expensive, plus you have to seam seal them. As for the EV2/3, I've read very few postings about them. One reviewer hated the integrated vestibule because snow always got inside the tent. Not to mention, how do you cook in it? I'm used to cooking in a vestibule with out a floor, just snow. What do you folks think?
