I guess I am more of a traditional turkey hunter, I predominantly use box calls and friction calls. I have used diaphragm calls and really do not care for them; I just enjoy making my own calls and using them to hunt turkeys. Between the two types of calls I can make any type of turkey vocalization that is needed at any given time. I would not consider using a "store bought call"; I used store bought calls and had some success, but which I switched to custom calls my success rate went up dramatically.
