That's a beautiful call. Thanks for sharing the picture.
I was thinking about the ebony/ebony combo for an aesthetic reason. But I asked because I also want the call to play well, even if it's a decorative call.
Inlaying slate might be a good solution. I buy my slate discs from Grassy Creek. I don't see slabs on their site. I'll drop them an e-mail, though, to check.
Thanks.
Mike
