The intonation is good as well, in fact as good as some pro level C instruments I have played (except above the staff where my embouchure hasn't recovered after a 30+ year layoff, so I can't really say how in tune very high notes are).

I play at basically a good high school musician level; lead in some groups, last chair in others.

However, if you look at the tunnels through the pistons they are more obstructed (bumpy) than on a top level model which negates this advantage.
