One of the local techs here in long island, during a presentation detailing his key height/key dip setting procedure, said he likes to set the dip on the piano in something of a bell a curve, being slightly deeper at the ends and slightly shallower in the middle. This, he said, was to compensate for the gradual felt compression which will occur during playing, since the middle gets more wear than the ends. Just another idea for the mix. -Matt
