Have you thought about sewing a mesh perimeter skirt on it? I hardly ever use mine as anything but the pyramid shelter, and I might just "convert" it to a tarptent... I'm going to use it this summer to see how things go, then decide. I get a little spooked without at least 3 walls around me, so it's a pretty strong possibility I'll just sew on some netting and cut the corners off. We'll see...
