I have found a bit of Mandrin post which goes into this argument... we did it with golf club attached to train and heavy iron byron versus light iron byron... the answer is still the same... Mandrin is right!!!
I am not contradicting mandarin at all, in fact I bow to his knowledge...
I did say in my earlier post "perhaps".....
All I know is if you try and hit a six inch nail into a piece of Oak that has dried out all summer, you'd better use a friggin' heavy hammer.....

I have not followed all this so closely but I think the deal is that mass is a different thing than "effective mass."
Effective Mass and father O'Hara
The mass of a golf club is the mass of the golf club; it may not be altered during the course of play according to the rules of golf. Science states that you can not alter the mass of a closed system; the golf club is a closed system. Homer has brought us many creative and wonderful concepts; "Effective Mass" is not one of them. "Effective Mass" is what a good Priest delivers on Sunday morning.
Here is a little experiment to illustrate the point. Mount a golf club in standard address attitude to the bumper of your Chevy. Mount a second identical golf club in the same fashion to a large locomotive such as the Amtrak Metroliner. Bring both the Chevy and Metroliner up to 100 MPH and let the attached golf clubs strike a ball. Which ball goes further? They both go the same distance. Change the mass of the clubs; attach a club with twice the mass to the Chevy repeat the experiment above what happens?

I mainly have experience with Vector and Zelocity machines.
Well the Vector only measures ball speed and spin. Anomolous smach factors unlikely if everything else is exactly the same. ie. Squareness, effective clubhead loft, angle of attack...
Zelocity appears to measure the correct stuff
Perhaps I was barking up the wrong tree.

I think that one of Mandrin's key points is that the golf ball has small mass and exerts very little reactive force against the clubhead during impact... hence the chevy / amtrack golfball striking experiment is equal... but i think that he accepts that if we were striking something heavier ( eg. cannon ball) then it might make a difference... but even then not massive
Maybe.... wait for Mandrin to confirm or refute...

action = reaction
It does not matter if the golf ball is light or heavy, the magnitude of the force exerted by the ball on the clubhead is identical to the force exerted by the clubhead onto the ball, albeit in the opposite direction. Perhaps not quite intuitive but such is Newton’s third law : Action = Reaction.

in this scenario, the truck of course knock me out the further.
But what I am trying to say is, if the truck and the car have the same engin, would the truck still reach 30mph?
Please do not confuse the two. If you are using a 30 pound hammer, can you still hit the ball at 100mph?

.....
I thought this part of the discussion was centered around who imparted more energy into the ball, a "hitter" or a "swinger," not about the capability of generating more clubhead speed..
I simply stated that PERHAPS a hitter, by doing whatever it is that hitters do at the bottom of the swing, transfers more of the available energy into the ball than a swinger, for the same clubhead speed....

The Zelocity PureLaunch directly measures Clubhead Speed at Impact, Ball Speed and Launch Angle. I understand that they are coming out soon with new software that will also measure Angle of Attack, Deviation From Center Clubface Angle and Side Spin.
