Extensor Action, Right Forearm Tracing and the on plane Right Shoulder
I want to share something with others whom have struggled with combining Extensor Action and Right Forearm Tracing. Unless your right shoulder is on plane in the downstroke, it's too easy to screw up. Take my word for it.
IMHO, you cannot do the one properly (Extensor Action and Right Forearm tracing) without the other (on plane right shoulder in the downstroke).
