A local store is pushing Bach Omegas now. They are stocking them with 5C mouthieces. That isn't standard on the Omega, is it? I also have seen two versions of the Omega. One is a Tr200 and the other is a Tr300. They are only marked Omega but it is easy to tell the difference. If someone mail orders one how do they know which one that they are getting? Maybe the Tr300 said Prelude on it, but I don't think so.
