What is your opinion regarding the Flat Backstroke Shoulder Turn (10-13-B #2) and the rotated shoulder turn (10-13-C)?
I use the Flat Backstroke Shoulder Turn (10-13-B #2) in conjunction with the On Plane Downstroke Shoulder Turn (10-13-D #3). This combination is the Standard Shoulder Turn (10-13-A).
The Rotated Shoulder Turn (10-13-C) and its consequent Shiftless Hip Turn (10-14-C) is a 'low power' Variation and is normally confined to short shots.
