My main concerns are if it's truly as '4 season' as GoLite claims it is and if one of the larger models would be suitable for October weather in Alaska even if I have to buy the nest and/or the floor to go with it. I like the idea that I can get a tent big enough for both my wife and I plus gear plus a bit of room to be comfy while hiding from a storm AND have it be light enough to pack in without burden.
