Take a hard look at Six Moon Designs Lunar Duo. I am 6'5" and I'm pretty big all over so I was looking for quite a bit of space in a lightweight package. Ultimately I had to decide between the Rainbow, Double Rainbow and Lunar Duo. I settled on the Lunar Duo for the extra space…but I must admit I've been constantly looking for something between 16-30 ounces. 34 ounces seems a bit much for a one-man tent…but 34 ounces is lighter than the 43 oz Lunar Duo.
I'd be interested in hearing if at 6'5" I'd fit in the Rainbow, but I'm still not convinced that 34 ounces is the best out there.
Another option is the Refuge by Six Moon Designs. It is only 27 ounces and has a ton of floor space. It also comes in a 16 oz Cuben fiber, but don't plan on seeing it soon as it is being redesigned and won't come out until next spring/summer.
One other option possibly worth mentioning is the Mountain Laurel Designs MidDuo. I just saw it at Trail Days this weekend and was pretty intriged by it. It is a floorless pyramid-style tent, so if you are uncomfortable with bugs, perhaps you could get a decent floor (Gossamer Gear polycryo or spinnsheet). The DuoMid is $195 and 10-14 oz (depending on silnylon or Cuben) and the ground cover is 1.5-4 oz.
