I would agree with most of these comments as keeping the wind in your face is your number one goal! If you can do that your odds already went up. Secondly, I used to be a believer in all this scent control stuff and I had a ton of scent blocker clothing and I am not sure that I believe in it that much anymore... Not saying it doesn't help, but I focus on staying down wind and haven't really had an issue of animals smelling me if you pay attention to business... Movement as stated above is the key! If you are motionless you are golden - simple as that! This year the bull I shot was coming down the hill towards me and I was sitting in a shortsleeve shirt with no face paint on or anything to cover my arms and I waited until my bull went behind a tree before I drew at 15 yards and he never even knew I was there. So once again if you don't move and get the wind right you are going to be fine.
As for the camo options all my camo is in Realtree AP.. I thought it blended in rather well this year in the timber and I will continue to use it next year..
