Rush, only if you limit your students. I am only referring to academia that do not accept anything else as being worthy and pressure the students into submission............. I have no heartburn with players that make the Bach choice for themselves. I used to play a 72* ML Bb and still have a 229H L C. Fine horns. I wanted more colors in my collection and that led to additional manufacturers like Selmer, Monette, and a bunch of more "obscure stuff". I do not believe the lies about blending. There is greater differences between players - and that is what causes blending issues.
