I'm a beginner caller and have had a lot of fun this offseason learning and playing with diaphragms and the bugle tube. What call are you chewing on and why do you find it preferable over others? I have a small/high palate and the phelps calls seem to suit me better so far. The grey phelps and phelps maverick are what I'm producing my best and most consistent tones with. Interested to see what everyone else likes and why...
