I prefer the 2P tent. At 6'3", a 2P tent is really a 1P+gear tent for me.

I tried using an MSR Zoid. It was an attempt at a true 1P tent. It had a good sized vestibule for gear, an dwas long enough for me. But I couldn't really sit up in it as it was a bit short, and I found it difficult to move around inside.

So I found lightweight 2P tents to use, and I'm happier with those. My other post in this thread has my experience with those - a Big Sky Evolution and a TarpTent Squall2.
