Re halo tie-downs: Hmmm. I tied my halo down INSTEAD of doing the corners, so the stake count was exactly the same and I didn't have that nightmare hassle of getting tape over the top, forming anchors from tape and PVC, etc. You still want to tape the roof panels together, but it becomes a rainproofing issue rather than a structural issue. Also, the stakes project from the middle of the sides rather than the corners, actually reducing the footprint.
Good idea to put metal under the straps at the roof/wall join, though.
