Here is my 2 cents. Most of the calls I've ran into, trying to find the call that I liked, would only do a certain percentage of the turkey's vocabulary. Since I'm a center air flow guy, I've stuck to v, batwing and ghost cut calls. The v cut would do yelping, purring. cutting and clucking for the most part. With the batwing same thing. And the ghost would allow me most of the vocabulary, but I had a hard time with the whine and whistles. Most of these calls came stretched with whatever the call maker used as their base stretch. Since I found I can run a ghost cut and get most of the vocabulary from a regular ghost cut, it was only fitting to try KLUK modified ghost cut call the Crying Karen and it hasn't disappointed! I started with the low stretch since I wanted a call that would be easy to blow and give me more control with the soft stuff and I must say it has made a BIG change in my calling. Brian and Nate, have in my opinion, went out on a limb and implemented some radical cuts (in today's market) and added 3 different stretches for more overall control of these calls. Maybe Brian or Nate will chime in and give us a little more insight to their rational behind their calls.
