The point of bringing things out of line is to create motion. Everyone can putt the ball quite straight, yet it wouldn't produce the power needed to play good golf.

With the back of the wrist inline with the wrist joint, one is only capable of producing about 45 degrees of motion without changing the configuration of the fingers. So whichever way you look at this, either you have an ineffective amount of motion or you have introduced a compensation.

A much better idea is to grip it in a way that allows one to wrap the fingers around the club and stay wrapped during motion; while also enabling the amount of motion needed.

Interesting but:

The Wrist Cock occurs in a Vertical Plane of Motion when using a Flat or Bent Left Wrist. As always, we arrive at a Flat and Vertical-ish Left Wrist at Impact. I also occasionally enjoy an ample use of Bent Left Wrist at the End of the Backstroke.

However. The #2 Accumulator is named the "Velocity" Accumulator because the Clubhead moves from point A to point B faster from the #2 Accumulator than with any other Accumulator. It has very little to do with "Around the Circle" Clubhead Speed (10-2-B Grip).

CF Uncocks the Left Wrist and by "Extension" the Clubhead gains Ground Speed. Extension would be the same for both the Flat Uncocking Wrist and the Bent Uncocking Wrist considering both to be Level at Impact. I would assume that the Residual Velocity used by the #3 Accumulator (Throw-out) would be the same given that the Clubhead reaches its Max Speed from Uncocking almost as soon as its released. The #3 PP and Right Forearm guide the Secondary Lever around the Pulley.

Law of the Flail. The Left Wrist is "Flail-Like". It's held to gather with a bolt.

In fact, at Impact, the Left Wrist is Vertical and the Clubhead is traveling/Uncocking "Down-ward" and when the Left Wrist Rolls past Vertical, it's traveling to the Right as it moves from Level to Uncocked. Severe deceleration.

However, Jamie Sadlowski uses the 10-2-D Grip and his Left Wrist is "Totally Bent" at the Top of his Back-stroke. He Uncocks into the Ball. His Wedges are Aligned at 0 degrees and he swings (Clubshaft) on only the Plane of the Right Wrist Bend, The Right Forearm Flying Wedge. Amazing stuff. Look how he bends his Left Elbow to keep the #2 Accumulator on the Plane of the Right Forearm Wedge and thereby keeps the "Pulley" in addition to Uncocking. Homer said that he thinks that Acceleration is another velocity factor. If that's true, then this guy proves it. Jamie isn't only applying the residual Velocity of the #2 Accumulator, he's using all of the Velocity.

But, "Drive for show, putt for dough".
