Here is a crazy idea. 1) Learn how to blow a call. Clucks, moans, hils, murmurs, all the basics. Throw all the fancy $hyt out the window. Most of it doesnt kill a goose any better than a standard cluck anyway and most guys cant consistently blow those notes when they need/should. If you are still using reference words while calling you havent mastered the basics and need to practice more. 2) Pick a brand, any brand - theyre all basically the same anyway. Tune it so when you blow a standard cluck it is as close to sounding like a real goose as possible. If you need to go higher, blow a higher note. If you need to go lower, go lower. All this carry four calls on your lanyard bs, high pitched calls, low pitched calls etc is laughable. If you have more than than two goose calls on your lanyard and you can only make certain notes on certain calls you need to practice, not buy more calls.
