My tip would be to do your scouting while you hunt. When you get there just set-up in a spot that looks good, who knows, you may guess the right spot and put a bruiser down on your first trip to the stand. If not, just adjust your set-ups after each hunt,sure, scouting and preperation are a big part in hunting, but IMO luck is more important. I have patterend deer and figured out exactly what they were doing, just to sit in stand and they never show up. I have also had set-ups that just looked plain crazy and stupid that were very effective. With limited time, your best bet is to just be out in the woods!
