I would recommend that you wear a Ghillie top (assuming that you are using a ground blind). Last year, I had a 6 point buck broadside from me at about 30 yards...I was holding out for a bigger buck

. He had no clue that I was there, I just blended into the surroundings. I just moved very slow and all was good. Another thing that I would suggest is that you use the Dead down wind products...I have had extremely good luck with this stuff. Do a search and you will find a review of it.
