Thanks to Craig for his advice but unfortunately it is not quite the
solution here. I know about the importance of the dampers lifting all
at once and I have spent about 2 hours making sure that they lift as
equally as if they were one. We always make a special point of this.
There must be some other more intriguing solution to this problem,
does anyone have any other ideas?

For those who didn't follow, the problem is that I cannot get the
sustain pneumatic to lift the dampers properly or with a different
adjustment I cannot get them to damp properly. There is simply not
enough stroke in that system.
