I used to kill a lot of turkeys with mouth calls --- then about 25 years ago I started making box calls. It's funny but now I will carry a couple of different boxes to the woods. One that will gobble, and a cuttin call with a great fall off. I figured it up last year, and out of the last 13 birds harvested, I used a mouth call one time on an old stubborn bird. Become proficient in a different type call, say a trumpet and a box and you won't miss the mouth call. In a lot of public woods they work better to those anyway. They become numb to mouth calls cause all the young guys are hammering them with mouth calls. You will enjoy the change also. Just my opionion, Im sure there are others out there.
