for the last 10 years or so i've been doing the bivy bag + siltarp(summer) or betamid/megamid scene, but it seems i always get dumped on by the weather. especially after my last three trips with mixed sleet, snow, rain in spring and rain + bugs the rest of the summer for about 19 days out of about 3 weeks, i find myself longing for the comfort of a double-wall tent. my old nf mountain 24(?) is still servicible, but a real pig to carry. my other tents have been run into the ground long ago.
i picked up a nemo obi1 for 3-season use, and on my last trip it worked well enough at slightly less weight than my bivy+tarp. now i'm looking for a new winter/mountaineering tent. i don't need to rehash the singlewall/ doublewall pro's & con's debate, or need info on biblers or integral designs, etc. and i know i can shave 2 or maybe even 3 pounds off my old nf mountain with some of the new double-walls. however, the stats on the nf assault 2 look pretty impressive on paper: low weight, "drywall" "technology", includes detachable vestibule, & at a relatively reasonable price. i used to have a single-wall tent about 20 - 25 years ago which was usually wetter inside than out. i don't expect miracles, but i was wondering if the assault 2 might actually have "dry walls", relatively speaking. the problem is that i've only been able to find about 3 user reviews. 1 said they hadn't had any major condensation issues, another said it was weather tight, and another said the listed weight was correct. encouraging, but not enough to base a decision on.
if anyone has had any exprience with it, i'd be real happy if they could weigh in the pro' & con's.
and on another but related topic, i've seen reviews re: the bd first light which seem polarized between saying it's drum tight or you might as well sleep in the rain. is this an old version/new version issue?
and while we're at it, any rab summit "shelter" users out there?
any and all input will be welcome. thanks in advance, phil
