I own a spitfire, it was my first tent when I got into bp-ing. I've had zero problems with the thing really. Pretty easy setup, decent ventilation w/ the peak vent, decent amount of room at mid-tent for pack, etc., and the materials are all pretty beefy compared to my contrail (obviously). It's not super light, but it's not obscenely heavy, and as far as I was concerned, was a pretty decent value for what it is/cost.

Only real "problem" I had with it, was that sometimes I'd shift towards one end of the tent, resulting in either my feet pushing on the mesh, or my face really close to the mesh/fly. One resulted in cool feet, the other resulted in condensation. Dotting or striping the floor with some silicone probably could have prevented that, but there's definitely not much wiggle room for tall individuals in there. I'm 5' 11" at best, and there wasn't much room for error before I was touching one end, especially if I was on a thick inflatable pad.
