I have mine pointing south, the reason is they can get sun all day if they wont it and another reason is for the south winds to blow in to the loft on them hot muggy days in summer. there is a tree line in back of my loft that blocks the north winds in the winter not geeting as cold for them, I also think this tree line helps them train harder when loft flying. They go up over the trees then down on the other side run about 50 yards or so then back over and repeat over and over works for me. I hope this helps. Ed
