I personally use a different calling style than most people in this state. You always hear how less is more when it comes to calling and from my experience the only cases in which this is true is if the person blowing the call is sub par or concealment issues. To me the louder the nastier the better. If ya'll are as serious about meat hunting as proclaimed in previous comments i recommend checking out a keyhole style call. Here is a video of someone i believe to be the best duck killer alive blowing a keyhole. Everything you hear in the video is used out in the woods.
