Yeah, I'm a mid fan, too. They are steep enough to do well in moderate snow. If you can only afford one shelter, I maintain that a mid is a good do-anything choice.
I detest inners, though. I just use a light bivy- it replaces both a groundsheet and bugnet, and will resist any light spray that might miraculously work it's way under the tent walls, for <6oz. For 20oz a DuoMid is a palace for one person, and can be pitched using a trek pole as the center pole if you put a rock under it.
The only TarpTent I have owned was a Moment- which was actually quite AWESOME and pitched wicked fast but I wanted to simplify things so I went mid. I never used it in snow but the reports say that it does ok in moderate loads using the optional longitudinal pole.
