10-7 (Plane Angle Variations)
The corresponding Chapter 7 Translation can be found HERE.
Plane Angle Variations are about what plane(s) the golfer swings upon. In the previous translation post we talked about the various plane angles the golfer can use. This post deals with whether or not the golfer changes planes and what plane changes they make. It's similar to Jim Hardy's 'one plane vs. two plane' swing, but it's not made nearly as important as Hardy makes it and there's different types of 'one plane and two plane' swings. Homer Kelley calls changes in the plane 'shifts.'
ZERO SHIFT - Golfer stays on one basic plane angle throughout the swing. Whether it be the Turned Shoulder Plane, Elbow Plane, Turning Shoulder Plane, etc.
SINGLE SHIFT - There's only one shift here and Homer is particular about what shift occurs. The golfer goes from the elbow plane to the TSP in the backswing and then stays on the TSP in the downswing. I have a 'Single Shift' swing.
Popular instruction would claim that my downswing is very 'steep', but the Angle of Attack actually is not that steep and I'm very much on plane in those swings.
DOUBLE SHIFT - There are two shifts here, but in particular the golfer goes from the elbow plane to the TSP in the backswing, then shifts again BACK to the elbow plane. Contrary to Moe Norman swing advocates, Moe had a clear double shift in the swing and is not a 'single axis plane' golfer.
The double shift I find to be very common on the PGA Tour. It allows the golfer to better eliminate the possible Over the Top move and thus when most PGA Tour golfers struggle with swing plane, it's usually getting too far under plane.
TRIPLE SHIFT - Shifts from elbow to TSP in the backswing, then shifts to a very vertical downswing stroke by getting to the Turning Shoulder Plane. I tried to figure out what golfer uses a triple shift and could not find one.
REVERSE SHIFT - It's a 'Single Shift', but in the opposite direction. So the golfer goes up the TSP on the backswing, then shifts to the Elbow plane on the downswing, very much what Tiger is doing right now with his swing.
THE LOOP - Like the single shift in that the golfer starts at the elbow plane, but moves to the Squared Shoulder Plane. This requires a very flat shoulder turn. Not a very advisable Plane Shift to use and to pull it off, you have to 'loop' the clubhead over to the Squared Shoulder Plane.
THE REVERSE LOOP - Golfer goes up the Squared Shoulder Plane and then down to the elbow plane. You could argue that Fred Couples uses a 'Reverse Loop' although I believe he uses the Turning Shoulder Plane on the backswing instead of the Squared Shoulder Plane. Still, the concept is similar.
THE TWIST - Golfer lifts either the wrists or the left arm vertically and straight back so they get on the Turning Shoulder Plane. They then come down vertically on the Squared Shoulder Plane. Homer Kelley states that the golfer has to have flat shoulder turn on the downswing to execute the 'Twist.'
