Jim, I was saying that if you want to make a decision about what shank is best, do it based on sound. That's what I have done with great results. I don't need to know how they create a better sound. I have my ideas, but it isn't worth pursuing. I found your tests interesting, but not what I consider useful when selecting a shank. I want to know what tonal characteristics a shank will produce. That type of testing can only be done by actual acoustical tests. Why don't you ask Kawai to prove it to you that thinned shanks create a better sound? They use thinned shanks on their new Shigeru grands. Thinned shanks are in use by many technicians. I don't believe the people who use them really care to know how they make a better sound. They just know a better sound is created. It seems to me technicians have gotten too caught up in trying to be scientists and can't remember the simple days of just trying something and seeing if they like it. That's the true test.
