I have had a Lunar Duo for a couple of years. VERY spacious for the weight. I am looking at "trading" in for the new Lunar Solo. Originally thought my wife would join me backpacking but no joy there. The Duo requires two trekking poles for setup (SMD does sell poles separately). If you go to backpacking sites (backpacker.com, backpackinglight.com...) and search against "Lunar Duo" you will find some very detailed reviews and discussions.
