The closer a mouthpiece comes to fitting your personal physiology, the greater the results you can expect to achieve. If you have thinner lips, you'll probably want to go with the standard 17mm size. All Stork CM series French Horn mouthpieces have a medium deep cup depth and an inner diameter of 17mm. They are available in 6, 8, 10, 12, 15, and 18 bore sizes.
