Agree with Craig's comments about Ryan's website.
I guess ultimately it comes down to how well you can live in your shelter.
Pyramids are not new, going back to the Native American Tee Pee. Over 20 years ago I had a Chouinard pyramid. I have a Wild Oasis, which is kind of a Mid.
I remember one winter night with temps below 20F in the Chouinard. No condensation on the sides, but solid sheets of ice. Ugh. But I will admit that pyramids can handle some pretty extreme weather.
I dislike the center poles... big time. Forces you to sleep off center and closer to the sides. Of course a duo provides more room for a solo hiker. and the crossing poles let you sleep in the middle.
I have had many tents, and I keep coming back to tarps and the 8' X 10' general size work great for me as a solo hiker in most 3 season use. And I normally use the A-frame set-up. Currently I have BPL Nano Cuben. Not ideal in heavy snow.
So I usually sleep without any shelter. For 3 season wet weather I prefer a tarp; and for winter snow a winter tent. This year I will be experimenting with a Scarp 1.
