Tim, I did not say that stiffer shanks sound better. I said that octagonal shanks of the same cross section as round shanks are not measurably stiffer, and that the round tapered shanks that are on the market are significantly stiffer and stronger than the octagonal ones, without being significantly heavier at the end where it matters most. That's what the original question was about. I also said that if you can prove to me that octagonal shanks sound better, I will be the first to go to work to figure out why. I'll now modify that to say that if you can prove to me that thinned shanks sound better, I will be the first to go to work to figure out why. Sincerely, Jim Ellis
