13-B is a flat backstroke shoulder turn which according to the book, put's the shoulder on plane for any plane angle with a flatter angle than 10-13-C Rotated Shoulder Turn.
10-13-C moves the shoulders in a "normal" path at right angles to the spine.

10-13-D "On Plane" Shoulder Turn requires either B or C above in the backstroke with the right shoulder moving toward impact precisely on the downstroke clubshaft plane.

Is 13-B superior to 13-C in a general sense?

I've been working on this component and in my experience, it is much easier to get the right shoulder on plane in the downstroke with 10-13-B. My pattern includes a turned shoulder plane downstroke swing.

Thanks,
