I would set your decoys up on the opposite side of the field that he comes out in and than sit on the other side away from your decoys around where you think he will come out. Set them up about 45 to 30 min before light and do little to no calling. He may be able to see your decoys from a distance and come out but if they are to close he may be to weary of them. Sometimes if the hunting pressure is to much turkeys get decoy shy along with call shy.
I used this set up last year on a group of toms and it worked like a charm. They would come out on this pipe line and look and strut around but once the decoys didn't move for some time they would just move on. I set the decoys up where I have been seeing them from and moved down the pipe line about 100yds (around where they were coming out) called towards my decoys a few times and than just let them come in. 30 min later I shot the one at 40yds 21lbs 10 1/4" beard and 1" spurs. There is nothing more exciting than out smarting an old long beard. Good luck and let us know how thing work out.
