For one or two people?
The 2+ “StratoSpire 2” is 44 ounces, 1.3 kg. Almost 3 pounds. Kind of heavy. I never used it, but those sides look pretty vertical if you’re concerned about high winds.
I like the pyramid shape of the Silvertip – not as much interior volume as other shapes, but that shape does really nicely in the wind. The Black Diamond Mega Light has been our go-to shelter in the Aleutians (“Birthplace of the Winds”) for several trips now.
It’s been a long time since I’ve backpacked in a crowded area, but so many thru hikers, especially on the AT, caution that it’s harder to find a spot to pitch a larger tent.
Note that wind resistance of a tent can be greatly enhanced by guying it out from the middle of each panel. Does it have attach points for guy lines and did you bring enough cordage with you? I always bring 25 feet of 130-pound-test braided Dacron halibut fishing line with me (only 6 grams) and I’d bring 2-3x that if I wanted to be prepared to guy out a shelter in all directions. PM me if you want some – I’ve got a few thousand feet on a spool (halibut live very deep).
Edited to explain: I didn’t link to the Mega Light. BPL did that automatically. Which I’m fine with, I guess.
