I love using a 3C mouthpiece for jazz playing and commercial work when not playing the lead part. However, as a player with larger lips, a traditional 3C does not provide the comfort I need to cover high and low ranges. This mouthpiece feels like it jetstreams my air column. Even though it isn't a lead mouthpiece, the way Marcinkiewicz mouthpieces are set up, my high range is very free and easy.
