I was lucky enough to get one of the first of the 2009 Gossamer Gear/Tarptent Squall Classics. It's a really neat tent, pitches taut quite easily and is very streamlined. It has a center zipper closure for the beak/vestibule which I love--no more velcro! (I really dislike velcro.) The sides of the bathtub floor pull up neatly all the way around--no sagging--far better than any other tarptent-style tent I've encountered.
Yes, it's a really snug fit for two. However, for me plus my 80 lb. dog, it's more than adequate. I'd call it a tent for one plus (one plus child or dog) rather than a two-person tent, and I notice that GG no longer describes it as a 2-person tent. Two people who want the light weight and don't mind snuggling closely will be OK, though, as long as only one sits up at a time (if both occupants want to dress or exit at the same time, forget it). I found that it works just fine with the front pole at 115 cm. instead of the recommended 107 cm., which gives a little more headroom. As mentioned, two 25" pads will not work. Two 20" pads will be cozy but will work. EDIT: Two big and stout people will definitely want a larger tent!
I had to abort my recent Wind Rivers trip due to my dog's getting sick. I therefore did not have a chance to test it in a real storm. If we'd stayed on schedule, it would have had a real test at 11,000 feet--wind, rain, hail, snow. However, the Squall Classic did hold up to quite a few heavy wind gusts and to moderate rain. I sprayed it for about 30 minutes with a high-pressure hose to test my seam-sealing before I took it out, and not a drop got inside.
It's really easy to get a taut pitch so it doesn't rattle in the wind. GG suggests putting the tent into the dryer, with air only (no heat) and a few tennis balls for 10-15 minutes. This softened it up a little and removed any noise issue.
I am waiting to review this tent until I've had it in some real storms, but couldn't resist commenting here. There seem to be some misconceptions about spinnaker fabric (I had some too), but so far I find it as strong as silnylon (my dog, before he got sick, took some runs through the guylines) and quite definitely waterproof.
The Squall Classic is definitely smaller than the Tarptent Squall 2 (which I also have), but is of course considerably lighter and more streamlined.
