Tested my GoLite ShangraLa 3 on Kodiak Last week. Winds were forecast at 40 knots on the coast. I can honestly say they were much much higher in the mountains. The teepee took it all. I was impressed to say the least. Good shelter.
Use some intelligence when picking a spot, and use some intelligence when staking it. I stayed wind free, and dry. Compared to HIGH dollar tents, and heavy heavy tents.. I was extremely impressed.
I was even more impressed considering the report Roland gave us of the goat hunters using a bombshelter with the same forecast.
