I have produced the following series of images that may have relevance to this discussion.



In the top image, I have adopted a neutral grip and I am holding a short iron so that the clubshaft is parallel to the ground and the clubshaft is at right angles to the left forearm which is parallel to the ground. One can see that the clubface is parallel to the back of the left forearm and back of the left hand. Note that my left hand is slightly cupped - simply due to the fact that my left wrist is in a neutral position (neither palmar flexed or dorsiflexed) while holding the grip, but when I hold a rounded grip, my FLW becomes slightly cupped.

In the middle image, I simply lowered my left arm so that it is about 45 degrees to the horizontal. I have kept the clubshaft parallel to the ground. Note that the degree of cupping has increased.

In the lowest image, I have deliberately palmar flexed my left wrist in order to obtain a FLW situation when my left arm is at 45 degrees to the horizontal. That causes the clubface angle to change.

I think that these images have relevance to the golf swing - because when the left arm is in the mid-dowswing, the left arm is angled downwards so that the left hand is below left shoulder level. In that situation, I suspect that the left wrist can only be really flat (when the clubshaft is on the inclined plane) if the left wrist is slightly palmar flexed. I personally think that Tiger Woods seems to be palmar flexing his left wrist slightly during the downswing, and that seems to keep his left wrist in a FLW situation during the downswing.

What do you think?
