[pianotech] Baldwin grand repetition spings

[Al Guecia/Allied PianoCraft]

Doug, keep in mind the TouchRail by Scott Jones. The unit with heavy springs will easily reduce the down weight by 20 grams. If you are going to the SERC in Charlotte, John Chapman and I will be doing a class on the TouchRail and we will have a demo piano.
