Ric, Besides grounding the stage truck so that the big "springing" arms don't absorb a significant per-centage of the pianist's and piano's energy there is the "Under-Lid" to consider. Seems that I heard about that on this list. Someone built a rolling box with one side low, and the other side up to the bottom of the piano. The box was rolled under the piano from the lid hinge side and reflects the pianos energy out to the audience as well. Perhaps someone here is the one who mentioned this and can send us some pictures...?
