I will take a partial attempt at it and I am sure others will have some good observations too.


"-At impact half of my front leg was forward to the "line" it had at address.

Outward knee moved all the way over to my left knee (left handed golfer).
- Left knee straightened out in the back swing. (not entirely but almost).
- Spine angel increased (tilt!) in the back swing (slightly) and decreased in the downswing. But still tilted away from the "target" at impact.
- Both Hip turn and shoulder turn looked well over 45/90 degrees. Maybe 55/100 or so. Both *** and back where facing the target at the top of the back swing.
- At impact both shoulders and hips looks pretty square to the target.
- My head moved 1-2 inches in front of its original position at address. Almost staying behind the ball.."

You must be over-swinging quite a bit. Your forward knee should never go back that far. Hip turn should probably be no more than 45 degrees as anymore unloads the tension you build up in your rear quads and front lats. This stretch produces the majority of your power. The more the spine angle remains constant in the back swing the better; but, that is not to say your head will not move back slightly. Results there vary slightly between a one plane swing and a two planer.
However, your head moving ahead of the ball at impact kills the built up potential in your swing and causes all sorts of grief.

Try only rolling your feet flat on the ground to the inside on the back swing and rolling your rear foot to the inside on the downswing. Position your rear foot perpendicular to the target line at address. This will shorten up your swing and restrict hip turn building up that desired tension previously mentioned.

Have fun getting better!
