I'm wondering about some pros and cons to the downswing being on the TSP.. including impact. Are there any specific components or accumulator sequences that would be necessary?

not sure where this can go but a little discussion on it might trigger a few questions. thanks

You should read my Book, "1001 Problems with the Elbow Plane".

Consider this:

1. Normally, the Elbow Plane requires a Delivery Path Shift. You can (but almost impossible) Trace the Plane Line after the Shift. Until then, no tracing. But this is overshadowed by a bigger problem. Hand Path and Clubshaft Plane are different until Release. That means while the Hands trace one path, the Clubhead is tracing another. Elbow Plane Golfers need to find "The Slot" or "Groove". With the TSP, the Hand Path and Clubshaft Plane share the same Angle throughout the Downstroke and Impact.
   
   
2. Shallower Planes require the Left Arm to move away from the Chest earlier than Steeper Planes. The Shallower the Plane, the Earlier the Release. Early Release is a Cause of Throwaway. Therefore, Shallow Swing Planes Cause Throwaway. An Elbow Plane is a Shallow Plane, therefore the Elbow Plane Causes Throwaway.
   
   
3. Elbow Planes are notoriously Pivot Controlled Hands Procedures. This means that the #3 or #2 PP trace the Pivots Rotation, not the Plane Line.
   
   
4. Elbow Planes rely on Pivot Speed. TSP relies on Downstroke Acceleration Sequence.
