Thanks for your reply. I think the solid inner will be a September order for me. It's still very pleasant at 10,000ft and the mesh will be good till overnight temps are consistently below freezing.
I've watched your video a few times but only now realised that you didn't follow Henry's instructions. You secure a pitch lock corner first; then the other three corners that correspond to the inner. Next the poles are put in place. The outermost points of each vestibule are secured last. That makes perfect sense to me, even though I had no problem with Henry's sequence. I'll try your method tomorrow.
As to my wind direction question, if I understand correctly you recommend pitching the ridge line perpendicular to the wind (my option 2). The ridge guy out points extend the line directly into and away from the wind. I concur that looks like the strongest pitch, with the narrowest surface area to the wind, even though the fly angle is steeper than my option 1.
Much appreciated. I'll be testing the SS2 later in the week, and I'll post my feedback to your suggestions.
