I don't use anything without a floor. First, I don't like bugs crawling over my face, and second, I always am concerned about rain seeping into the sleeping area (after all, I live in Washington, where the state flower is a can of Rustoleum spray paint!)! I'm either in a Warbonnet Blackbird hammock, or in a KUIU tent. If I'm hunting as part of a shared group, I'm hauling their Mountain Star 2person, which weighs 3 lbs 3 oz with the carbon poles. If I'm out by myself, its their Ultra Star 1 person, at 18.9 ounces. I also opted for their tent pole on this one. Bathtub floors, very well ventilated, lots of room, and exceptionally lightweight. I'm impressed by both the quality of the materials and the construction. And of course, the lack of bugs...
