I've owned and ran several floorless options, as well as regular bathtub floor style tents. I own a Seek Outside Sunlight 2P which just pitches with 2 trekking poles(discontinued but similar to the Silex), the Seek outside Cimarron, Easton Kilo Carbon 2P (discontinued), and several from Kelty. It seems like the Nemo Osmo is almost a spitting image of my Easton Kilo Carbon 2P, besides the door is located on the side instead of at the head of the tent. But the have the exact same Pole Configuration. I love that Easton tent, but it's one that's advertised as a 2P and it's definitely not capable of 2 adults. I'm not a huge fan of floorless shelters until the temperatures drop because of all the bugs. Once the temps drop and it's time for a floorless shelter and a stove, they definitely have their place. The reason I say I'd like as light as possible while still maintaining performance is because ounces make pounds very quickly. Some things are worth the extra weight... Just trying to find a shelter that really shines, has minimal condensation, is lightweight and backpacker friendly, and will withstand the elements so I my gear is never the reason I come home from a hunt early.
