Jon, when you say overstriking, do you mean the hammershank has passed through the vertical and the top of the shank is closer to the string than the bottom is? That is what I would call overstriking. I have never seen that on a properly functioning upright. The reason I have been given for the required UNDERstriking in verticals is to enhance the hammer re-bound time and to reduce the tendency for the hammer to fall towards the strings Hammer hanging on verticals is different than grands because [in theory :^)] gravity helps pull the grand hammer away from the the string. As I understand it.
