It depends on the style of music you play. I prefer a hard rubber mouthpiece like a Morgan Classical, Selmer Paris C*, Larry Teal, Vandoren Optium, or Meyer if you want a classical sound. On the other hand, if you want a jazzy sound, try out these hard rubber mouthpieces: Jody Jazz, Selmer Paris Supersession, Morgan Jazz, Beechler Bellite, or Phil Barone New York. If you are interested in a much brighter, warmer sound than the hard rubber mouthpieces provide, then the metal mouthpieces will take care of that. The Jody Jazz ESP, Otto-link, Phil Barone Contemporary, Vandoren V16, Claude Lakey, or the Sugal are all excellent choices or metal mouthpieces. Make sure you test the mouthpieces before you buy them. Try out the different sizes and choose the one that best accomodates you.
