In 2-H, Mr. Kelley states that the Head Pivot Center is "recommended", but it is "not at all mandatory". That certainly sounds to me like we can have our choice of Head Center or Between the Shoudlers pivots without a lot of serious dissent from HK.

I would appreciate a discussion of the pros and cons of each and why certain players would be better served selecting one over the other. There must be reasons why the Head Pivot Center is recommended by HK, but there also must be reasons why it isn't mandatory.
