This is a really excellent review, which has come out at exactly the right time! I am trying to find a well-ventilated, wind-stable shelter for me and my 80-lb. dog to replace a Six Moon Designs Lunar Solo. The LS is a bit too cramped for me and the dog, and the two of us together definitely overwhelm the ventilation system. Your article has given me a lot to think about!
The one item I'd take issue with is the "5" rating for ventilation on the Lunar Solo. On a foggy, drizzly night on Washington's Olympic National Park coast, my Lunar Solo, with just me in it (no dog), had significant condensation. My Tarptent Rainshadow 2, pitched right next door, with three people in it, had no condensation at all. I'd give the Lunar Solo a 4. On the other hand, the Lunar Solo is outstanding for wind stability, is very waterproof in drenching rains and hail, and deserves its higher ratings there. In fact, I'd give it a slightly higher wind stability rating than you did.
