I was out tuning today and it suddenly hit me that I hadn't mentioned  
the bottom covers. Yes, these are 8 B's, all with undercovers, and  
all with 2-tank systems.

With no systems these pianos changed 45 cents with the changes of  
season. With old single tank systems they still changed more than 20  
cents. Now with 2-tank systems and undercovers, one changes maybe 6  
cents but that prof isn't so good about watering. The rest stay at  
pitch.

I agree about the top covers. Bottom covers should be much higher  
priority than string covers. I have a D with a 2 tank system, and top  
and bottom covers. (It is in a challenging environment with heat/AC  
vents blowing across the top of the piano.) This piano, even with air  
blowing across it all the time, stays at pitch within a couple cents.  
I credit the string cover in this particular case.

Dean, as for whether these are overkill, I don't think they are. If  
for no other reason, I like the 2 tank systems because they hold  
twice the water, and might not have to be watered as often as single  
tank systems, which is an important consideration at the university.
