Bob, if I'm not mistaken I believe the OYOA guys are using the Be The Decoy system with the goat hat and t-shirt. Looks like a solid option in some situations, but I have no experience with them. I did use the Heads Up last year with good results, but it was definitely more of a learning experience being that it was the first I had tried it. Opening morning of Kansas season I pulled a great goat off his does and got him to 60-65yds. I judged him to be a little closer and shot under him. Prior to that I had some good encounters in Colorado with it. We hit the very beginning of the rut and most bucks were just staking out their territories, but weren't chasing yet. They would come into 80-100yds for a look, but that was it. I'm going again, unfortunately earlier than last year, but if they're acting the same, the plan is to sneak a little closer and have a buddy show the decoy from 75-100 yards behind me.
