That being said, I have seen plenty of examples of very very tight bushings on pianos that have seen many seasons, and I cant help but think there is some measure of friction added to the mix.... tho whether its significant or not is another matter. I think Ron has it really... they help deal with flagpolling... and not a whole lot else. That is unless this influence on tone buisness has some merit to it.
