I'm selling my RPC mouthpiece because it is a little too open for me. I'm use to something a little smaller, so that's why. It plays like a dream and has a huge, fat, robust sound you cannot get anywhere else than RPC. I have used a mouthpiece patch since I bought it about a year ago so there is practically no damage to the bite plate. My starting price is $200, but we can talk. If interested, I am more than willing to email you some pictures.
