I got to use my Ss1 in Ireland at the weekend and both nights had to pitch it on slopes as any flat ground was completely waterlogged, no big deal as was able to prop up my pad with some gear underneath it.
As I was pitched on open mountains the two doors really helped as the winds where coming from all directions, the ripstop inner curtailed
Any drafts, I tend to use the rip stop inner far more than the mesh one.
I was jealous of my buddies Sl3 though.
