I happen to know Jimand while he is an amazing teacher your chances of getting a lesson with him are just as good as winning the lottery.
his teachers are very good though. especially at Weston Hills in south Florida
I would have to say the Ernest Jones book "Swing the clubhead" which was first published in 1952 is a timeless instruction book and also a collectors item.
Ernest Jones principles of the swinging motion simply many thing that are over analyzed today and sometimes obsolete.
