Well I just recieved my Lunar Duo in todays mail, and I am really impressed with its initial size. The sheer volume of the floor looks amazing, and I really like the area that is devoted to bug netting/ventilation.
I am a bit concerned that I will have to learn to pitch it in more "forgiving" locations as the floor does look a bit tender, and I have the std floor option.
Overall I'm really liking what I see.
