I have used the montana decoy with tremedous success i have the braodside decoy it really works we have been hunting with two of us and we set it up behind the shooter in front of the caller we try to leave a place for the bull to show his stuff while giving the shooter an opportunity try to set it up so that the bull will not see it from along ways off or he will want to come starit to it wich will almost always be right over the shooter (murphys law) we have had plenty of times this has happened. If the area allows try to set it so that the bull won' t be able to get in line with the decoy and shooter. If i had to buy another one i would definately buy the hind end version if for no other reason than safety. We called in a hunter in colorado that was intent on shooting our cow. Had it been a muzzleloader it might have been scary. Other thought is that the hind picture makes the bull think this cow is leaving or that it might be another bull i know of a buddy that swaers that this decoy makes the bull circle around to try to find out what he is looking at and almost always gives a good shot opportunity. He likes to set this one a little different they set up to the sides instead of front to back and do no calling after the bull sees it. Good luck.
