...if you fixed the CLUBFACE first, a pretty good player (most hookers are) would hit a RIGHT-to-RIGHT shot and the lesson would be in the "potty" very quickly.
When I fix the plane line first, they hit a hard pull, usually are quite surprised it doesn't hook MORE.
Then we fix the HIPS-HANDS-CLUBHEAD sequence and get every thing to my "magic line" (Don't ask, it'll be in Never Hook Again 2.0) and go have a Diet Coke, cuz they are fixed.
