I ended up ordering the new SMD Lunar Solo. Got it last Thursday and took it out for an overnighter last weekend in AZ's Superstition mountains, and I'll be taking it out again this weekend for a 2 night trip. For reference in the below pics, I'm 5'6'' and use a 1'' pad. My quilt is sized for my height. And my dog is 60 lbs. Her gray foam pad is about 20'' by 30''.
Here are some pictures:

Foot room:

Me sitting on my sleeping pad – I have about enough room to kneel under the tallest point.

Plenty of room for my dog. She has enough room to stand up and do her circling without touching the tent (although her tail does hit it if she's got it up):

Outside right (had trouble getting this side tight):

My initial impressions of the tent are quite good. These pictures are from my 2nd time setting up the tent. I was able to get one side quite taut but had trouble getting the other side to be taut as well. I am sure with some practice it will get better. That said, the pitch was perfectly useable and did not take me long. I think the shape will have no trouble shedding wind or rain, and I expect the mid-panel pullouts can provide me with extra headroom or wind/snow resistance if needed.
Before seam sealing, the tent itself weighs in at 22.2 oz. Given that the tent is made of silnylon, should be fairly storm-worthy, has a large amount of interior space, and has a large vestibule, I find this quite amazing; the $200 price tag makes its even better. There are lots of subtle things I like about the tent too: the main canopy has no seams, the way the pole tilts inwards a little and is tensioned through the floor, the little mesh pocket inside, and the high bathtub floor. Ventilation seems adequate, but I am sure I will have condensation if the conditions are right, just like with every other tarp and tent I have tried.
Compared to my Tarptent Rainbow, I feel I have more floor space for my dog and I, although headroom is a bit less over all. Will it work for someone 6' tall on a 3'' thick air mattress with huge feet? Probably, but things might be tight and you might have to use the mid-panel pullouts.
I am considering replacing the webbing tensioners with linelocs. Not sure if this will save any weight, but it would be nice to have longer and reflective line.
