How does the right shouldr turn in the backswing? Horizontal to the ground or to the spin?
How should it swing in the downswing ? Where sould it be at impact?
Backswing
General direction--back, in, and up, away from the ball
It should turn as flat or as steep and as much or as little as you need it to.
Downswing
General direction--down, out, and forward, toward the ball
The sequence of movement will depend on what you need. Some people need earlier axis tilt, while others need the shoulders to retrace their backswing movement early and add axis tilt later.
