The advantage of a 3-valve compensating system in a school isn't that it weighs less, though it might possibly, but it's that there's not a some several feet long extra loop of tubing that only almost does what a three valve compensating system does, that tubing wanders all around the instrument, and a bunch of braces are required to hold all that snake of tubing in place. 4th valves offer a good solution to 1-3 and a crappy solution for 1-2-3. Below low E - a pitch which is still stinky sharp with four non-compensating valves, the only valve combination that serendipitously works out is 2-3-4, so we're back to falstones (as with the non-compensating 3-valve system, again...and what percentage of school children are going to pull slides, even when told to?
You're a smart guy, and - even if you don't agree with me - you understand my points:
- Even if three compensating valves somehow doesn't weigh any less than four non-compensating valves, it's a far less fragile setup... the thread topic being ridiculous damage.
- three compensating valves does a better job - referring to the B-flat world - with low E and B natural - pitches which are not as well addressed with four non-compensating valves.
Other reasons for four noncompensating valves could be "I'm used to four non-compensating valves" or "I don't like top action", but neither are a particularly good argument against an already good-playing fiberglass sousaphone enhanced with three front action compensating valves for school use indoors and outdoors, agreed?
