I know a lot more about gunstock woods then wood used for turkey calls. That said, in the gunstock world Quartersawn wood is preferred because its the most stable and less prone to warping during the drying/curing process. In the gunstock world the rule of thumb is wood should be air dried instead of kiln dried as kiln dried wood had a tendency to be brittle. That's the reason those folks who make high class wood instruments only use air dried wood that has been well cured/seasoned. Simple reason is because its not brittle, not warped and it sounds better. Lastly drying times are generally air dried for 1" of thickness and then air dried for another year or two after that so its well cured/seasoned. Accordingly, wood used on a pot call should be air dried for at least 3 years so its good and stable and the sound quality is were one wants it to be.
