Right on the money- for Single left wrist action- since there is no hand motion during the stroke and the pivot keeps the clubface On Plane and imnpact fix alignments intact.
But... if Standard Wrist is used where the hands are turned in the backstroke, they better roll back on the downstroke. Shout it out- You must Prepare to Roll on the plane line before execution. Homer says that a swinger will feel as if the HH is one big turn and roll. But the hinge action is after impact- full of preparation.
A Swinger using an Angled Hinge, since it is NO Roll, will feel no hinge action but a swivel/roll late into follow through.
