WOW. some seriously good changes there!
Gonna have to agree with the guys (what a surprise... not)
DEFINITELY need to maintaing the stable axis 1-4. Head going down, causing you to stand up and straighten legs too fast in downswing, also to shallow the shaft out.
1. feel NO TURNING, just STAND UP P1-4.
2. left arm needs to be only 15* in at P5. (Its too deep, inhibiting the ability to shallow the shaft, so you 'standup' faster, as a better player to compenstate.)
This will straighten the LOC into the ball and reduce the roll.
Some pics to come for you.
