The Lagging Clubhead Takeaway And The Right Forearm
The Lagging Clubhead Takeaway (Unpublished 7th Edition 10-9-A) does not preclude the Right Forearm Pickup (7-3). In fact, the Swinger absolutely should use his Right Forearm to take the Club up the Turned Shoulder Plane. Otherwise, he will have no choice but to begin on the Elbow Plane, and this mandates a Shift -- always hazardous -- to arrive at the Top on the Turned Shoulder Plane.
This particular application of the Right Forearm Takeaway utilizes Extensor Action (moving from Bent Left Wrist to Flat Left Wrist per 6-B-1-D) in conjunction with the Lagging Clubhead Takeaway to set up his "Swinging Motion" (per 7-9) and Drag Loading (per 7-19-3).
Hitters can use the Lagging Clubhead Takeaway, but they are better served using a Non-Lagging Clubhead Takeaway to set up their Drive Loading per 7-19-1.
