Very well written article as always. However, I am not a fan of this type of shelter. I find in my experience that it offers very little protection from snow and rain. Once the wind starts (and it never seems to blow from one constant, uninterrupted direction), that rain/snow will be right in your face. I know the roof is put at a very steep pitch to shed the rain/snow, but I find the large open area to be a big problem. Also, the shelter does not trap much heat, and mostly serves as a reflector. That forces you to use a large fire to keep warm. I know it's a popular shelter design, but I have had very bad experiences with them. That being said, each type of shelter has its own set of problems.
