Thank you, 6bmike. The extensor action in the backswing during a hitting type proceedure seems very physical and conscious. But when using a lagging clubhead type backswing the mere touching or pushing of the pressure points in the hands against one another has the swinging clubhead doing the work.

Is this right thinking in this area of the backswing?

Extensor Action is just the pull on the Left Arm in a straight outward linear direction. It is the same in either stroke. Think of it as 'motion glue' of the Flying Wedges.

A Hitter has by nature a more conscious stroke. All control. But EA is no different. Stretch-Pull of the left Arm by the Right Arm just like Swingers.

A Swinger at Standard Address will use EA to snap into a Bent Right and a Flat Left wrist. It is still the Right Arm taking the club up in a RFT- not EA, since EA doesn't ever move the Left Arm in any direction but straight outward from the Left Shoulder.
A Swinger using a Lagging Clubhead Take-Away is still a hand control take-away since it is the clubhead lagging behind the hands. EA is still applied by the right arm as the elbow folds. The clubhead doesn't do the work- it is just the object of momentum.

In either take-away- both still a RFT- it is the Right Forearm that is lifting the club and Left Arm, not EA. The Right Arm is not only driving against PP1 and PP3 but is pulling outward- linear- on the left Arm- the OUTWARD is EA not the driving. This gives structure to the stroke, Flying Wedges and Power Package.

Long answer- sorry
