re: Golf swing question

If you all would allow me some analogies from other physics ...

a. A second baseman has a quick back swing on a double play. A pitcher has a very slow back swing. The pitcher throws a lot harder.
b. A snake has a slow back swing a very fast strike.
c. If you've ever used a bull whip it's a slow coil and then fast forward motion.
d. An archer takes a very slow draw back and then releases fast.
e. A discuss thrower starts very slow and accelerates.

It seems to me that a slower back swing would result in more restored energy converted to kinetic energy.

The only exception I can think of is badminton. The back swing is very fast because the racket is so light. Perhaps modern golfers can do this because the new golf clubs are so light.

I had some 1964 Ben Hogans. I think the driver weighed twice as much as the one I use now.
