I have no idea to be honest. I started restoring my piano a while ago, but now I realize that I need more experience in playing different pianos. Maybe I should have posted this question in the pianist zone, I'm sure the pianists played a lot of different pianos so it would be nice to hear what they prefer. I read that older pianos had a shallower key dip. But I'm curious of you have enough room for dynamics with a shallow key dip, but maybe that's really a strange thought and there's not a lot of difference. I think I'll go with 10mm key dip.
