i would say a quick swingers start down is exactly whats happening stretching it to the max, my hips get very aggressive and arm gets stuck behind me, i tend to be very 'FAST' with my swing. im pretty sure i tore my rotator cuff. not that it matters but is there anybody on tour that swings on the elbow plane, ive seen some flat swings but none below the shoulder

Practically all Tour Players use the Elbow Plane from Release through Impact and to Finish but at the Top of the backstroke they were on a steeper plane.
