Actually even club-fitters admit that is not simply a case that tall people require longer clubs and more diminutive players shorter.
If you think fitting works for you fine but nobody can conclusively prove that it will make a difference to all players.
Nor did I suggest that was the case.
I did suggest that the same club was unlikely to suit both of us equally well, if it suited either of us at all. I'm also not claiming that buying a set of custom made clubs will see me, or anyone else winning tournaments hand over fist. All I'm claiming is that having a set of clubs that fits me better gives me a better chance of producing my best golf more often, just as adjusting the driving seat to suit allows me the best chance to drive the car well. It's not an easy game & I don't see the need to make it any harder than it needs to be.
You wouldn't go to play wearing the wrong size shirt, trousers or shoes; so why would you go with the wrong size clubs?
