I've been inside a Seedhouse SL1 before. I do like the size and weight of it, but I do really like the door being on the side of the Copper Spur as well! I'm willing to add a bit of weight for the Copper Spur UL1 to have the comfort and convenience of it. As earlier stated, it's going to be basically be my "home" for a while.
Any thoughts on the Klymit Inertia X-Frame?
