Well, it's in there, with a Slide hip turn.
The rotated shoulder turn says to use a shiftless hip turn. And under shiftless hip turn it says "tends toward a soft stroke with emphasis on accuracy. It can produce an on plane downstroke shoulder turn only with the rotated shoulder plane angle." (As defining a turned shoulder plane angle versus transport only?)

Something does not compute. I think shiftless hip turn is not always required with rotated shoulder turn. Only when using it for transport-only as in 10-13-B. Awkward wording. Unclear in both the shoulder turn and the hip turn.
It's in the thread on 7th Edition Changes but hasn't been discussed.

I'd stick with Standard shoulder turn, flat back, on-plane down. TSP angle. 'specially at my age.

When you are saying "flat back" does this mean horizontal to the ground or to the spine?
