+1 on the quality. I have 2 Tentipis, terra nova, TNF ve 25, MSR Storm King, Macpac etc. All awesome tents in their own way and nothing, with the exception of a tentipi which is a very different animal, is as well built as the Soulo. My North Face westwind, which has done nearly 20 years service, is pretty close but the tunnel design is not as user friendly as the freestanding Soulo. It’s the only tent I’ve seen which is genuinely freestanding too – no reliance on pegging. You can use rocks/bags/skis on the guys if necessary but no pegs needed for the tent to be pitched (although they obviously help).
It is also very warm – solid inside unlike the mesh of the Voyager which lets winter wind whistle straight through. Ventilation not great in the summer in the Soulo, but what do you care? You’ve got a Voyager for the summer!
Akto – I’m not a fan personally. I’ve camped with a few and you have to pitch them spot on IME otherwise they flap like crazy. They also are dependant on good peg placement. They are much lighter than the Soulo though.
