Instruments played on weekly basis

[kathott]

I try to keep up on the four tubas (CC, Eb, F, BBb), and am curious as to which instruments people regularly keep ‘in service’?
The approximate amount of time I perform on each over a year is as follows:
CC: 35%
Eb: 30%
F: 25%
BBb/euphonium/bass trumpet: 10%

On a normal week, 3. My personal CC, and my issued CC and F. Used to include a few trombones in the rotation as well (Tenor and Bass), but they have been on the back burner for the past few years.
