Yodeli your on fire and lighting up the whole board, keep going while your hot.

So the thrust, as directed through the pressure points 1,2,3 (4 being up in the arm/chest) is On Plane, Forward, Down, Out and towards the plane line after impact, after low point and until.......................when? Both arms straight? The club switches ends? The club points at the extension of the plane line on the horizon line?

Or am I getting mixed up, thrust being a straight line?

You're right OB, I'm boilling like termonuclear lava !
that's because I'm pasionnate about Golf and happy to help back others as they did with me on Lynn's wonderfull site!

Back to your question:
1-L-15: The club starts up and in after low point but the thrust continues Down Plane during the Follow-Through

6-C-2-A "...the Accumulators will not be released by this action until the Right Elbow can straighten (ie: both arms straight, the end of the follow through). Even then the Clubhead Lag is still maintained -- it has NO Release point."

Also, check this video (Hitting vs Swinging) on the Gallery and listen what Lynn says starting at 1:14.
This should answer your question about when the swich ends.

The club points at the extension of the plane line on the horizon line?

Or am I getting mixed up, thrust being a straight line?

The direction of your Thrust and the direction your shaft is pointing are two separate things.
The more important is to put you mind on directing your thrust (ie: where is my PP#3 travelling?).
Your clubshaft/clubhead will follow all the time!
However, it is interesting to monitor where the clubshaft points at to check if the clubshaft lies on plane... (if not, it tells you that you're not moving PP#3 on the right track...... try again, look, look, look!)

As a result, the clubshaft should always points at the base of the plane line (either the clubhead or the but of the grip) to the horizon line.
Remember that after both arms straight, your left arm will swivel, allowing the shaft to "replane", the but end of the grip pointing now at the base of the plane.

But all this is a byproduct of sensing PP#3 :

• going down plane (aiming point) - yes, thrust is a straight line - spear a fish.
  OR
• tracing the base of the plane - tracing a straight line from the horizon to the horizon.

Two way to direct the thrust - two intentions - but funnilly enough, same travel of the hands! Your preference.
