Il Corn Fed, thanks for your post because you just saved me from a bunch of typing!!My findings were exactly as yours. I think that the Primos Buck Roar is a much better call.
On Nov. 17th. I had a nice 9 pt. come running in chasing a hot doe. She came through about 45 seconds before him on a run. Here he came behind her. He stopped where she went out of the edge of the woods and ran across a small open field to another section of the woods. Right before he took off to cross the field, I hit the Roar. Man he froze and threw his head up and looked my way. He looked back her way, then towards me, then back her way again. I hit the Roar again and that was all he could take. man he stiffened up , blew up and the hair on his back and neck stood up. He let out a long deep grunt of his own and trooted my way. I mouth grunted and stopped him and layed a perfect double lunger on him. About 10 seconds and and 35 yards later my season was over ( yea, we get one deer here!). So I have no doubts that the Roar works at the right time on the right deer.
