I am considering buying a tent for my wife and I to use on our AT trip. I have always been a hammock hanger so I am looking for feedback from experienced tent sleepers. I am looking at 3 person tents for the 2 of us because i am a big guy and would like the extra room. I have done a little bit of homework and 2 tents have caught my attention. They are the Tarptent Rainshadow and the BA Fly Creek UL 3. Any feedback on the merits of one tent versus the other, single wall versus double wall, waterproof abilities, ventilation, ease of set up/take down and warmth are welcomed and appreciated. If there are other tent suggestions please speak up.
