Base of the Neck vs. Through the Head "centers"

[brianmanzella]

Another great answer, Lynn!

But, in case anyone else would like to answer, here is a couple of points to consider about my answer:

If you use the "through the head" pivot center, your swing center—the left shoulder—travels—in a shorter arc on the backstroke.

Also, if you use the "through the head" pivot center, the possiblity for a circle delivery path, becomes far greater than the "base of the neck center."

But, the "through the head" picot center nearly assures the better player that the shoulder turn won't be too flat.

As far as the angles on the pin, I choose to only comment on the thesis of this thread: Is one PERFECTLY still pivot center, TECHNICALLY superior to the other...

...and why?
