7-19 from the 3rd has some GREAT stuff . . . Good reading here!
Power Package Assembly is not normally completed until all Lag and Loading is established. All Lag types are in danger of Clubhead Throwaway. So Lag Loading not only includes, but is, Throwaway Prevention Procedures. That is, procedures which will forestall any kind of premature or unintentional disspation or reduction of either potential or existing Thrust or Velocity.
This is the most common cause of Power loss. Thrust and Velocity are easily generated but getting them to the ball is the stumbling block. So more detail and more emphasis than usual is given to this category to assure maximum opportunity to understand it.
the correct Clubhead Lag Pressure "Feel" is a deadweight, a status quo - a deliberate, unvarying, "steady as she goes"-an unrevoked, unreversed, stable, permanent Inertia. Exactly like dragging a wet mop through impact. A steady pressure that sustains the Line of Compression. A careful nursing of the Clubhead Feel.
Incorrect Clubhead Lag Pressure "Feel" does not set up a steady driving pressure but a convulsive, impatient THROWING pressure, guaranteeing Clubhead Throwaway. Rolling and/or Uncocking have the assignment of throwing the Clubhead. Lag Pressure is totally inert. The slightest "pushing away" will produce Clubhead Throwaway. When you find yourself swinging fast whether you want to or not, you are contending with Clubhead Throwaway and it could be induced by improper Clubhead Lag Pressure Point action. And instead of "driving" the Club you find yourself "chasing" it - and never catching up with it. some players find it easier to maintain the Bent Right Wrist Feel than the Flat Left Wrist Feel, especially for replacing the Cocked Wrist Feel to offset "False Feel" Wrist action during the Release.
Using the Pivot (from the Feet) instead of Arm motion to set up Lag Pressure and Rhythm reduces the risk of losing them by "running out of Right Arm" and extends the Lever Assemblies to maximum Moment Arm.
