I use it all the time and focus (a little) at the entire ball. I see the ball, but am more picturing (in my minds eye), my rotation to the finish. For my swing I picture a complete finish (the club/arms and body rotation) finish at the same time*.
* Now the club/arms and body rotation must finish together to have been correctly aligned through impact, but they do not start or move together on the backswing. The shoulders move first and things windup from top down. Then as they unwind, they all should finish together with your body in balance. There should be no fall back or extra step to catch yourself if done correctly.
