Admittedly, my most used call to finish birds, and my favorite calls to play are not the same... My least favorite to use, but probably most used are diaphragm calls. If I could only use one call in the field it would be a diaphragm. Currently I like Hook's calls and Gooserbat custom calls, which are actually less expensive than many manufactured calls (including Zink or Woodhaven), next would be Woodhaven. No doubt that diaphragm calls are the most difficult to use, but can be some of the most realistic calls, and the easiest to put "emotion" or inflection into... I ain't that good, but better than most I have seen on YouTube (which ain't sayin' much). Another benefit to mouth calls is that you can carry a couple of dozen of them and take up no room in the vest... Try doing that with a box call or pot call... I love playing with a box call in the woods, and it is great for reaching out there, and for realism... I currently have an SS Call I really like, and Spring Creek makes a very reasonably priced custom call as well (no frills). Primos (I have a Heartbreaker) and Lynch World champion are two very good cookie-cutter calls... Lately I have really enjoyed playing scratch boxes (my favorite to play)... Great at the low end with very realistic clucks and purrs... Not as much volume as a box call, so it is not a "searching call." Definitely a two-handed call (comparable to a pot call)... It has a similar realistic resonance as does a box call, less loud than a box call, but a bit better for the finesse. Far more difficult to play than a box call, and probably about the same level of difficulty (or more) as a pot call. I have never really gotten into pot calls... I have heard hunters in the woods on them, and can immediately tell (as I can with many people barking like a seal on a diaphragm). Box calls have fooled me a couple times though. What do you guys like, and what do you not care for?
