Many in the audience will be experienced instructors who are invested in their own methodology. I suggest starting with 1-L Machine Concept.
Explain viewing the body as a machine concept and the three functions Clubshaft, Clubhead, and Clubface. Allow this to lead into Plane, Pressure Points, and Flat Left Wrist. I believe these concepts will arouse interest without threatening points of view.
Next cover the imperatives and essentials. To back it all up – Geometry of the circle!
Good Luck
