RE: Mouth calls
Totally disagree with the double comments. Get a triple with cuts and you will learn how to call just fine if not better. You will get sounds on any of them but with the 3 reeds you can get better sounds right away. If you keep it in your mouth and practice you can move your tongue around and put more or less pressure, move your tongue in and out, side to side to find the best sounds. Remember to use the air from the diaphragm not just blow it from your mouth. Like huffing air on a pair of glasses. After some time you may be able to constrict the air with your throat and make it a little higher pitched for the begining of the yelp then open it up for the back end. Good luck.
