Jim,
I've never been a fan of "pyramid" tents. Don't like poles in the center of my tents or winter tents W/O floors.
I've seen Todd-Tex tents (in a store) and it seems like a decent fabric. Good to hear positive reports on it.
After using lots of winter shelters, including tarps when hunting, I like a good dome tent and a big vestibule. Tunnel tent would be my 2nd choice.
One thing that still bothers me is the amount of moisture we can put into a Thermarest over the course of a winter week when we "top it off". Not a good thing IMHO. Thermarest needs to market a stuffsack/pump for winter camping.
Eric
