Though I mostly play soprano, I play alto in a concert band as well as other occasions here and there. My alto is a YAS-23, which is a decent horn, but not quite as solid or ergonomic as my Yanagisawa soprano, especially in the high register. (Yes, I understand we're talking apples/oranges here, but bear with.)
Looking for suggestions as to what could be done to make the best of YAS-23. First thoughts were palm key D extension, as well as slightly altering the shape of the low alt f# key to improve chromatic/F#/C# runs.
Setup is Selmer S80 D* + Gonzalez 3s. (Still need to get a decent lig.)
