I have 3 identical pianos (same size, same scale, > same board thickness, same ribbing, same bracing, same rim structure, > same belly rail, same type of hammers, etc.) with 3 different types of > bridges.

It likely *is* the bridges. What do the three different bridges weigh, do you suppose, and how does the MOE of the three compare? Ron N
