We use the Jack Wolfskin Tundra III. You've probably made up your mind on a lightweight free standing dome tent but you just might want to consider a tunnel tent.
The big plusses are a lot of room in the vestibule for all your gear, its a three person tent so we have plenty of room in case we need to wait out a storm, extremely stable in foul weather, can be pitched outer tent first (great if you're pitching the tent in heavy rain) same in reverse (the inner tent is tucked away dry in the panniers before we get out into the rain), it has a side entrance right into the sleeping area which is great for warm weather were we open both entrances which creates a draft (both have mosquito nets). The big minus is the weight, just over 10lbs
We've only used the Tundra III for a couple of years now without any problems. Our older tent was the Worlds End RT, its bigger brother.
