To me wind is very important, especially from a tree. Eventually your scent hits the ground some distance away from your stand. I've seen this first hand. I have a stand where I'm 28' off the ground. I expected the deer to be coming from the west and had a west wind. Well, the deer came from the east, down wind from me in an open field (picked beans). They picked me off from 200 yds. One more positive reinforcement to not hunt an iffy wind. I will only hunt a stand if the wind if perfect for the stand. Don't kid yourselves that by being high in the stand that the deer won't notice you. This only works if the deer are too close to you that the wind blows over them.
