I just recently bought a Dukoff D7* alto mouthpiece. It plays amazing, but i'm a bit curious as to what size facing is the D7*. I've looked at many different facing charts, but none of them have the 7*. I know the 7 is .080, and the 8 is .085. I'm guessing the 7* is maybe around .083, but I want to know for sure. Thanks for your input!
