I currently use the MSR Hubba 1P and find it's a great tent, but I am a rather large guy coming in at 6'4 and about 265. The Hubba can get a bit cramped inside for me. I also sleep very hot and I find that when I have the rainfly on, the Hubba gets very stuffy inside. There isn't a ton of ventilation.
I recently met a thru-hiker up at Mount Rogers that was using a Tarptent Contrail. He absolutely swore by it, but I would like to get a couple more opinions that might be floating out there before committing to the purchase.
Do any of you have experience with or are currently using any of the Tarptent models? I like the Contrail because you use your trekking poles and it appears to have decent ventilation all around the bottom. As well as being a bit roomier than the Hubba.
