Many people jump to the conclusion that the Left Wrist is Arched when they see this picture. But is it really?
What could be happening is this. David has his Aiming Point very far forward. This naturally delays the Release to the extent that the Clubhshaft cannot reach its in-line condition with the Left Arm before the Left Arm is vertical to the ground. This explains how he can have the ball after the Left Shoulder and at the same time not have the Clubhead ascending during Impact. All without an Arched Left Wrist. So here's something to think about for those who say that Low Point is always opposite the Left Shoulder when you have a Flat Left Wrist.

It may look unorthodox, but I think placing the ball well forward is a great way to learn how to hit down. Also teaches you to how to control the direction of your Thrust from the Top. Do this for a while, then place the ball back to a more 'normal' location, you will suddenly find it very easy to hit down.

I love your analysis Leo, and I must admit that I am guilty of stereotyping this "look" to be the product of an arched wrist.

As such, I have altered my original reply to your post accordingly.
