I know that the FLW has been discussed alot (anatomical / geometric / etc ) but it stuck me that the appearance of the wrist is really a consequence of the forces being transmitted through it IMO.
The COG of the clubhead will line up with the left shoulder when the club is at bottom of swing - right?
If, whilst holding your club, somebody were to grab the sweetspot between finger and thumb and stretch out the club and arm so that they form a taut straight line... then observe the left wrist condition....isn't the appearance of the left wrist in this condition FLAT ?
It is the longitudinal direction of pull that is undeniable and the force controls the appearance of the left wrist.... does FLW 'happen' if we let it ...or should we actively 'hold' it flat??
Simulating the forces in a correct swing might be a better way of describing the appearance of the left wrist...especially to newcomers??
