Quick update - I now have a Copper Spur and am quite happy with it.
Here it is pitched freestanding on a NH tenting platform. I am 6' and fit comfortably in this one - although not as wide as the tarptent contrail. It has ended up being my primary because it is freestanding and very easy to set up (I often hike with a friend who always, about 2 hours into a hike with the start and end points well defined, will start saying "you know, if we push it..." and we sometimes end up pitching tents in the dark. There is room to sit up and enough vestibule for boots on one side (small door!) and a pack on the other. The weight is as advertised, 2lbs 14oz. (in a stuff sack). Ventilation was good, no noticeable condensation - since the tarptent has all mesh sides between the floor and walls, I would get cold in the early AM it was getting below 60F at night and I stayed warm.
