Just wondering if any of you use teepee style shelters such as the GoLite Shangri-La 3 or something similar. How wind resistant are they? The American Plains Indians used this design for hundreds of years in the most windy of environments, although their teepees had more internal structure than backpacking teepee shelters. To be more specific, would there be much shelter material deflection in a steady 30mph wind? It seems to me that pitching direction would not be a big issue unless the door was pitched into the wind creating an air scoop. This design should be an advantage in swirling winds. I suppose a big disadvantage would be the pole right in the center. I've never used this type of shelter, but I've seem a few in the back country
