I usually play everything on a Bach Mt. Vernon 7C. I tried one out for fun a year ago and it just worked for me. I play everything from Symphonic Band to Jazz Ensemble to Principal in an Orchestra. Somedays I play in all three of these groups. On Mondays I play in a performance class and play pic on a 7C with a cornet shank. I basically listen, think of the sound I want to produce, and I seem to blend well with these groups. I think playing what is most comfortable for you and having a concept in your head of what you want sound like works best IMHO.
