Ted, Thanks for the info. I guess the "Limp Left Arm" was a play on
words. Glad that you emphasized the extensor action. Somewhere
in the downswing or at the top the left arm would have to become
rigid to give the primary lever some structure. Can't push against a
limp rope or limp left arm. As Hogan said "one arm of the two always has to be straight to maintain the radius" I find your observation that
extensor action aids to keep the left wrist from arching to be very
informative. I will hit 500 ball today with the hitting thought.
Thanks again, Donn.
