I normally use a Bach 3C for orchestral settings, which is adequate and a great mouthpiece. You get a little bit more projection in all registers and it's a little bit easier to play. The rim sits more comfortably, as I do feel that the 3C 'bites' into my lip after extended time of playing.
Pros (over the 3C)
- Better projection
- Slight increase in ease of playing high (don't expect miracles)
- Comfortable rim
- Elegant and sexy design
Cons
- Takes a good amount of adaptation, you should be good in a couple of weeks.
Summary
Great mouthpiece for all around use, especially orchestra.
