I'm 6-2 and find the Lunar Duo is plenty long enough for me with extra space at my head and feet. It's huge inside for two people, with two large doors and vestibules, Fairly easy setup once you've done it a few times. 45 ounces sealed and with stakes. No separate inner, and we do get condensation frequently here in NC, but the space is worth it.
We do have a Zpacks Hexamid Twin on order. It's smaller than the Lunar Duo, so it might be a bit tight for two, but at 20 ounces it'll be a palace for me as a solo tent, and can hold both of us when we need the weight savings. Zpacks also makes a 20 ounce 2-person tent, the Duplex, with two doors and vestibules. Might be something to look at. Not sure of the inside length.
