This mouthpiece has a slightly flatter rim contour and is extremely comfortable. It was developed in my search for a good classical mouthpiece to use when I play symphony work. Quite a bit of my playing is done on a much smaller diameter with a different rim, so this mouthpiece facilitates that type of switch. It has a deep cup from the PATRICK 3C, but the rim inner diameter is closer to a 7. It also has the same back-bore and hole size as the 1 1/2 and the 3 so it retains similar characteristics.
