The CR5.3C uses the same cup, 27 hole and standard classical back-bore as our standard 5.3C, but has a Comfort Rim. This Comfort Rim profile is a bit wider than all of the classical models, but not as wide and cushioned as the commercial models. The CR5.3C uses the same cup shape as the 3C, giving it more overall cup volume for a big round sound. You still retain the benefit of the smaller rim size, but without giving up the sound of the bigger mouthpiece.
