Practically No difference....

Its been gone over a million times but in essence Mike down under is right.... Even if the shaft weren't relatively speaking "a noodle" making it virtually impossible to transfer any appreciable force to the club head during impact, the time duration is so small that the force has practically NO EFFECT

V = velocity = integral of Acceleration (this is basic calculus)

V = A dt .... where A is acceleration (force divided by ball mass)

where dt is the time the force is in effect (i.e. during clubface contact which is .0005 seconds max)

This is why I asked soulmanz what kind of force he thought he was capable of generating. It figures he being a know-nothing poser would not answer.

But lets say for argument sake the shaft is infinitely stiff (doesn't deflect under applied loads) and lets say and the golfer (your "hitter") could put 10 lbf into effort on during impact (totally unrealistic situation but just for the sake of argument of it lets assume its possible) Then how much additional velocity would a hitter's effort give the ball?

.0005 sec * 10 slug ft/sec^2 / (.101 lbm /32.2 lbm/slug) = 1.6 fps = 1.09 mph

He-man hitter picks up maybe 1.09 mph which ain't squat. Better to focus on proper technique then to subscribe to a debunked theory of the "heavy hit".
