theo,

On point one,
dont use harmon as proof, he book is terrible and so are his dvd's, he has VERY basic info, nothing exciting.



On point two
take a club and grip it with a short left thumb, bring it up to the top of the backswing and hold it there, now while in that position just lengthen the thumb
DId I say this was a panacea for a short back swing????? I just said this is why HOGAN did it. Most golfers loose spine angle, among other things that are more important to aid in shortening the back swing.

AND TO QUOTE HOGAN ON PAGE 32 SECOND PARAGRAPH
"I changed from what is called "long thumb" the left thumb fully extended down the shaft to a modified "short thumb" contracting my left thumb and pulling it up a half inch. THe "long thumb" let the club drop down to far at the top of the back swing and it made it really rough to get my timing right."

your thoughts, Theo "I Need help getting my foot out of my mouth" illogic

On point three,
Cupped at the top is OK if you want to make an extra move to be flat by impact

Glad you have read so many "experts books" but you have yet to mention a book I have not read and you would have to mention MANY more before you get to that point I guess you think you are the only one who knows how to read
