Keith, Listening and sequencing the shanks is very fast if done correctly. I don't agree with Grotian's sequencing method. I've been sorting low pitches to the bass end and high pitches to the top for over twenty years. One basic principle I follow is a low pitched knock associated with a movement within the piano reduces power. It is one of the main reasons I change front rail felt punchings. Hard felt punchings create a low knock that robs power from the sound. I find the same to be true with the pitch of the shanks. But as I have said before: to each his own. Grotian does it their way and that's fine. I know what works for me.
