I don't understand why the concept of wood under compression crushing cumulatively with big humidity cycles is such a tough concept.< It is a simple concept. I am of the opinion that it isn't a problem on the blocks I have direct experience with. Some of these pianos I am talking about got their blocks in the early 1980's. If I don't see any appreciable lateral movement of the pin through the block after 30 years, I am not going to let that be a determining factor in my technique. Ed Foote RPT
