First and foremost you mentioned something in your initial post that stood out to me.
Your wife is not use to it.
You also mentioned that the Allak double wall will be perfect... Seems like ya kinda made your decision already in a sense. This is not only about you enjoying your trip but also your wife.
I was looking at the Stratospire 2. Alot of mesh there plus from what I see the fly doesn't extend completely to the ground.
My #1 worry with this is spindrift. I have been I less than adequate shelters when the winds kicked up and the snow was coming down sideways.
Its not fun being in an unexpected snowstorm but it is even less fun literally being in a blizzard inside your tent. This can make for a bad trip.
Why leave it to chance?
Look, 3 season tents are dubbed 3 season tents for a reason. Same with 4 season models.
If you are possibly expecting 4 season conditions why even consider pushing the parameters of what the Stratospire is designed for? To save a lil weight?
You can make that difference up elsewhere.
Do I believe it will handle a snowload? Absolutely. I think most any tent now a days can handle some snow but that doesn't equate to inside comfort/protection.
The Allak will offer much more protection in bad weather than any UL tent. I mean, that is what it is made for.
If you know what hits the fan at least you know you are prepared for it.
It completely behooves me at times. I read reviews of some 3 season tents and see statements where the reviewer will say "the tent was horrible in the snow so only a 3 out of 5 for that."
I just laugh and think to myself "ya don't say it was horrible in the snow." IT'S NOT DESIGNED WITH THAT USE IN MIND...
maxx, I gotta be honest here. When people decide to roll the dice on the chance that things will be okay because they want to save weight I just shake my head.
Just take the Allak and make sure you as well as your wife have a great trip.
Heck, I forget if you have the footprint for the Allak(I thought you had it up for sale at one time) but if ya do just leave the inner at home. This will cut down on the weight and if ya encounter blowing snow/bad weather you will probably still be better protected than ya would be in a 3 season UL shelter just based on the Hille's design with the outer extending flush with the ground.
Just my .02.....
