They certainly feel spring pressure on pianissmo. When the notes are being
sustained it is necessary to press against the spring fairly firmly.

I agree that smooth operation and precise regulation will solve many of the
vertical damper problems. Still, with some pianos no amount of regulating or
spring pressure will ensure quick damper cutoff. Just as with the grand
piano damper system, a combination of appropriate mass and light spring
pressure will easily do what springs alone can't quite handle.
