Wondering what people's thoughts are on this tent. Im in the market for a 4 season mountaineering tent in the near future and have been mostly looking at single wall tents, mostly the Bibler I or Eldorado or the Integral Designs MK 1. Then I saw this. Not much more weight, and a double wall. My thinking is that in summer, and at lower elevations, in Colorado and Washington where I climb, it might be better. More breathable, better in the rain, and, for nice weather, i can lighten the load and take just the fly and a footprint. Also, its cheaper. Any thoughts?
