sorry, i also play tenor

Well...There really isn't a "best: mouthpiece out there, It all depends on what kind of sound you're looking for. I think the tenor has the most when it comes to variety of mouthpieces and sounds.Tip opening determines how free blowing the MP is. Wider tip opening equates to easier blow and added volume but require more control. The baffle is the roof of the mouthpiece chamber. A “high baffle” is when the baffle is built into the tone chamber, thereby reducing the chamber’ size. A high baffle gives a tone with more edge and brightness. Conversely, a “low baffle” results in a larger chamber and a somewhat darker sound. Some mouthpiece companies, such as Meyer, offer different combination's of tip opening chamber sizes. If you're looking for a brighter sound, I recommend going with a metal piece like Otto Link Super Tone, Guardala, or Ponzol. However, those can get really pricey. Some good hard rubber pieces would be Otto Link Tone Edge, Beechler Diamond, and Meyer. Those are considerably less expensive.Take in to consideration that it may require changing reed size too. The key is finding a piece that gives you a sound you really like. Good luck! -JDC

My suggestion is to try some out. Places like woodwind and brasswind (among others) offer trials on mouthpieces. You can usually get 3-4 at a time, and you pay for the return shipping and disinfecting for the ones you return. Or find a local band store that has a wide variety you can choose from and/or try out. What works for your buddy may sound like a fog horn under water for you. Also, if you go this route, be flexible to try different reeds out too.
