Ball position for shoulder stroke
 

Hey guys. I know this is covered in Alignment Golf but I lent it to a buddy of mine so I'm without it for the moment. My question is "Where do I position the ball with a shoulder putting stroke?" I dabbled with it yesterday with pretty good success... until I pulled a short one on the 15th hole. Then I started wondering if it was ball position and then realized I wasn't even sure where I was playing the ball in my stance. I think I was playing it just in front of center but not sure. Can somebody help me with this?

The swing center for that stroke is between the shoulders, so that's where low-point is. Frozen arms and wrists make it a virtual vertical hinge action, straightaway flight. Identify low-point and place the ball just after it, or close to it. Directly under the left eye is conventional wisdom, head centered.
The shoulders must move on plane. Pulls are shoulder out. Pushes are right arm straightening.

Awesome answer Loren! Thanks so much. That's what I was looking for.
