| Do you typically find, then, that when changing to a
| transition bridge that there is a maximum percentage
| reduction in speaking length that you are willing to
| undertake in order that the change in SPR doesn't result in
| too dramatic a change in the tone in that section?  It seems
| that the smoothest transitions (at least on paper) require
| quite significant reductions in speaking length in the
| transitions.  More modest changes which likely would have
| less impact on the SPR seem to mean compromises in the
| scaling through that section--though, I guess, not as much of
| a compromise as the original which caused one to consider the
| change in the first place.

Every so often I still hear some piano marketing guru going on about how this
new Peerless Model Exceptionale Grand has been designed and constructed "without
compromise." What it tells me is that the guru simply does not understand either
piano design or piano construction. 

Pianos, like most other things in life, are a product of compromise. And this is
certainly true where retrofitting transition bridges to existing pianos is
concerned. 

I use the smallest percentage change in speaking length on a transition bridge
that I can get by with to give me an acceptable timbrel blend. More and more I
am using the configuration shown in the attached photograph. A compromise?
Certainly! But I find I can achieve an acceptable timbrel blend at the expense
of only a moderate jump in inharmonicity. The benefit is that it doesn't stand
out aesthetically. Many prospective purchasers don't even notice that it doesn't
look quite original; just that it sounds immensely better.
