Many years of good luck with Sierra Designs and Big Agnes, no frills designs and solid construction...Went to MSR last fall in a solo tent and broke the pole out of the gate-that was a first. Vestibules are a must in my book, double doors too are nice ...but my focus is on weight and the second door usually looses. I will buy more from either of these two companies-esp. the Big Agnes Seedhouse II. The zip on the vestibule is a stretcher though.
