It sounds to me as if you and the bird have each other patterned. I would try something off the wall. Do you use decoys? If so maybe try and do the breeding hen and jake decoys. Or maybe set up closer to where he will roost and not call, just wait. Maybe not putting decoys out and not call ambush him. Maybe if you have a buddy that can help by setting him 30 yards away from you in the opposite direction the gobbler comes from and have him call. Try to get aggressive with him as well. They are quite a few things you can do. Lets face it if you kill this gobbler you will have mixed emotions. 1 being pumped because you scored and 2 feeling sorry for such a great competitor... Just my thoughts...
