Greg,
I have both the Contrail and the Lunar Solo and have used both in all kinds of weather–except snow (We don't get much of that in South Texas).
As far as weight- after you add stakes to the Lunar Solo (Contrail comes with them) and seam seal them they weigh within an ounce of each other around 26 oz.
You are right that the Lunar Solo may be more storm resistant in that the overhang of the roof extends almost to the ground and the more pyramid shape may spill snow and wind incrementally better. On the other hand I have gotten more condensation in the Lunar Solo and find it less well vented than the Contrail. The Lunar Solo comes with a zippered vestibule, which I find more convenient than the Contrail's Velcro one. The Lunar Solo really has only one way to pitch it, but it does come in two colors.
The Contrail vents very well and I have found it surprisingly condensation free in all but the most challenging atmospheric situations. The many different variations for pitching the Contrail are a plus as weather conditions change you can change the tent to accommodate. In the storm mode with the foot end carbon stays laid flat and staked to the ground the Contrail is sort of a wedge shaped pyramid. It can also be pitched with front and rear pole as an "A" frame.
This summer we took both tents to the Holy Cross Wilderness in Colorado for a week. No snow, but some rain. Both did great, but the Lunar Solo had condensation every morning and the Contrail only one night.
Foot room is about the same in both tents and should accommodate "clown feet" without a problem.
Head room should be ok in both tents also, although you have to be a little more careful in the Lunar Solo since the high point is in the middle one has a tendency to brush the sides when sitting up.
