My story is similar: After a correct start gripping as Armour advised in his classic How To Play Your Best Golf All the Time, I got 'sophisticated' and moved to the weak grip being touted in the popular teaching methodologies of the day. My left thumb ran straight down the top of the shaft. What a disaster.
Today, I would much rather see a grip err to the strong side (Turned to the right) than the weak (Rolled to the left). Especially with the left hand.
As far as where I rank the grip in the hierarchy of golfing components, one need only look at Homer Kelley's own Stroke Patterns (12-1-0 and 12-2-0). Of the 24 Components, #1 and #2 establish the Grip (Basic and Type). Any questions?
And in my own work . . .
Remember Annie's first lesson (post #5 above):
"First, I fixed her Grip . . . "
Great post as always Lynn. I hope that all on this forum appreciate what a wonderful resource you have provided over the years. Also, congratulations on the success you must be enjoying along with your ever growing stable of players.
