I been at it for a couple decades. I use a trumpet, some pots and boxes, crow call, tube calls and diaphragms. I just pick what calls I want to carry and go. I change it up depending on what the birds seem to respond to.
As for the wingbone or Trumpet type yelper, all I can say is practice practice practice. Be patient and remember it doesn't take much air to get a sound. Once you become proficient, a suction style yelper is a deadly tool for fooling old toms. Start trying to draw a cluck through the caller and progress to yelps, cackles and kee kees.
