A TarpTent Double Rainbow works for us 2 grrls - two doors, good situp room, reasonable weight, airy. Squall Classic is a lighter option if we're weight conscious (OK I've had it for a while!). Another TarpTent that's a similar weight to the Double Rainbow but has an amazing amount of room for 2 is the Rainshadow 2. I guess you need to think about your specific requirements/preferences (my GF likes 2 doors) and also regions where you'll be using the tent e.g. The Rainshadow has a much bigger "footprint" than the Double Rainbow.
I'm also keen to experiment with a Trailstar tarp and BearPaw Pentanet mozzie net.
Good luck with your tent hunting!
