My wife and I have been using a Haven for 3 years. It has plenty of room for two people. We have the silnylon version. However I am purchasing a Stratospire 2 for our trip to Patagonia in March. I think its' configuration will handle heavy winds better.
That being said, we will probably still keep the Haven since it is lighter. We have used the Haven on the West Coast Trail, Wind River range, Superior Hiking trail and the Blue Lakes area of Colorado and have never been disappointed.It is a really good tent.
