I hunted with some of the best callers on the Missouri river during the 60s, 70s. Ralph Kohler, Jim Kelly, Jim Eagleton and Calvin Metzler. None of them used anything but a single reed call. Either Lohman or Mallardtone were the favorites. Most of the calling was minimal. In my humble opinion overcalling runs more ducks out of the county than otherwise.
