7-2 Grip Types

note the A and B sections.

I did some "sweet spot" stuff down in the lab a while back.
I proposed a "hang the club on a thread" experiment here not long ago.
I have debunked the "sweet spot" is aligned by cf numbers of times.
There is no magic physics that align the clubface all by itself.
CF takes place on a FLAT incline plane and provides NOTHING significant that rotates the club/clubface about anything (the shaft or cog axis) lying on that plane.

Like to hear your opinion

I didn't understand your A and B - so tough for me to identify your point and know if I agree or don't. Here's my thought - as an object rotates in a circle - if the pull is strong enough then the object's center of mass will align itself to the center of rotation and maintain a constant relationship to that center as it rotates in a circle. So it's not closing or opening IN RELATION TO THE CENTER OF ROTATION - however for example in the golf swing it is opening (on the backswing) and closing (on the downswing)in relation to the ball/target.
