Agree 100% with Strutter and Gambling. To me there is no magic call and the closest thing to a magic call is the one you are most confident and efficient with. More important than the call is the amount of calling that you do and a super close second is the cadence in which you use that call. Some of the worst sounding calls I have ever heard in my life were covered with feathers and flew out of a tree. Dont put to much stock in sounding perfect as all turkeys sound different and like I said some of the worst were real hens. Pay more attention to rhythm/cadence and the amount of calling. Good luck.
