Is it just me, or is there a conflict of information here?...
OK so you "fix" the clubface...how?
Considering..
Most amateurs have a tendency to grip "strong"
Most Amateurs aim the clubface at the target (or that is there intention)...
With the above setup they still come over the top, with a too open clubface..
Now in addition, we know
At impact the clubface should be about 1.8* open and close to square by separation..
Now from what I have read here previously, you recommend:
A neutral grip (i.e. weakening most players strongish grips)
Mid body hands, which makes the clubface closed at address...
Now jack Nicklaus said the other day, "I have never seen any good player who sets up with the club facing directly at the target." This was during a discussion concerning the fact that most good players set up with the face open at address...
So you set up with the face slightly open...but hang on, what about mid-body hands, so the club should look closed, plus weaker grip which will leave the club more open.....
How complicated are we trying to make this game...
