It seems to me that swinging would hold up better under pressure, and over
time, less to "do" - just setup the machine and let it go.
That was not Homer Kelley's conclusion. Enjoy the exact words of The Master:
"I think Hitting is going to become far, far more popular than Swinging
with the real blood-thirsty golfers, the money-hungry golfers. They're going
to go to Hitting because it is...they have total control; much better finesse;
more positive control of Power; and less total body involvement."
"It is far more difficult to learn, but far easier to execute
when you get it. Oh, it's so simple! Nothing ever happens! Nothing ever gets
out of line! You just take it up and come down! And you can slam it as hard
as you want to if you stayed with this Right Forearm alignment."
"And you'll find all of a sudden you don't have to Throw the
Club. Just come down any speed you want and it just comes right through. And
not having to 'Rotate the Plane Lines' [Ed: to curve the Ball.] -- gee,
that's a tremendous advantage. But, it is harder to learn, but lots
easier to execute once you've learned it. Much more individual. You feel like
you're controlling every little ingredient."
