[Yoda]

The period of Shoulder Accleration from the top - is it both shoulders we are talking about - or is it the right shoulder for hitters and the left shoulder for swingers?

Right Shoulder Thrust - is that a hitter's item - or does it also apply for the swinger?

Always the Right Shoulder, Air, for both Hitters and Swingers. Remember, the Left Shoulder is not On Plane. Therefore, other than the Fix alignments (8-2, 7-8, 3-F-5, 7-2, 12-5-3 Section 2, and 2-J-1) the geometry of Shoulder Control (2-H) always deals with the Right Shoulder.
