CR Crossroads Game calls feedback?

[BTH]

This may have been covered before.. if so I apologize for the repetition. Does anybody have any of the CR pot calls? Specifically the red or green slates? If so how do you like them?
The gentleman that makes them is very responsive very polite. His calls look like nice craftsmanship that I can see. His wood and surface combinations are spot-on judging by well renowned call makers choice of woods. Thanks in advance
