Bigfoot-for 4 season, something that is 1-2 person, self supporting, big vestibule (a must), a couple of inner pockets (could be add-ons).

Current popular lightweight 4 season tent choices seem to be the Hilleberg Akto/Terra Nova designs, Hilleberg tunnel tents or the ID/Bibler/BD designs. Obviously there are others, but they tend to be heavier.

One problem with using trekking poles for support in winter, like with Henry's tents would be that if you go day snowshoeing or skiing, you have to take the tent down, so dedicated poles would be better IMHO.

I wouldn't expect a tent from Henry to compete with bomber expedition tents, but something for mild winter conditions would be interesting.
