Hilleberg Niak – a lighter version?

All three of those would probably be good (especially with semi solid inners)

I would also say to consider pyramids with more than 4 sides – you get many of the same benefits as the two pole mids (smaller individual panels, steeper wall angles, still adequate wind shape) such as the Seek Outside Silvertip. They also make two pole mids like the Eolus/Silex as well. Or the (I believe discontinued) MSR Twin Sisters which has snow valences sewn on.

Another option are single skin mountaineering tents such as the Big Agnes Shield line or the Rab Latok line. And I personally also really really like what Slingfin is doing – they have some epic tent designers – internal guylines really do work in bad conditions and I highly recommending using them on any shelter and adding internal guy out points if your shelter does not have them. You can just sew loops onto the same exact spot the external guy out points are sewn to except on the inside.

Also there are many different semi solid inners on aliexpress you can mix and match with various shelters like the Gatewood Cape or if you want to use a small semi solid inside something like the above Silvertip. For group trips I often do Silvertip + dig out the snow below the canopy so that everyone can stand inside the shelter and then also dig out “couches” where people can sit or someone can setup a bivy or sleeping bag to sleep.

Repeat several times.
