Which way does the wind most commonly blow from? The answer doesn' t really matter! Wind changes direction and if you have limited yourself to only one stand location, you' ll hook yourself.
It sounds like you have identified the area of most common travel and the area you want to hunt; the scrapes. You should try to find at least 4 trees in the general area that will get you a clear alley or shooting lane. Beyond that, due your time in the woods and develop a picture of how when and where the deer are moving.
But, then again, with the rut on, a lot changes!
