Hard question. Hope to hear/read Homers exact words on the subject later on.
In my mind I compared the following:
1. Flat left wrist, straight plane line, clubhead lag pressure point and stationary head
2. Flat left wrist, straight plane line, clubhead lag pressure point and balance
3. Flat left wrist, straight plane line, clubhead lag pressure point and rhythm
4. Flat left wrist, straight plane line, clubhead lag pressure point and extensor action
And went with Stationary Head.
