Avery and list, Maybe I'm all wet, but my notion is that if you want to change the stack to correct over-centering, you'd raise the front, not the back. It's where the centerpin is in relation to the strings that matters (unless you change the hammer bore). And raising the back will affect the height of the centerpin little if not at all. And I don't understand your reluctance to reduce dip. You have what you might consider excess dip already. You have excess blow distance. Reduce both, and you're in better shape, no? Key dip is about the most negotiable measurement in all regulation, in my view. Let off and aftertouch are what is most noticeable (with aftertouch negotiable within parameters), followed by blow, and dip last. Regards, Fred Sturm University of New Mexico
