HH has greater clubhead travel - so would it be moving faster or slower... resistance vs. speed from face rotation. AH/VH has less travel and a slower rotation, so does the face move faster or slower with rotation/closure? we know what it does to curvature.

Accumulators move the Center of Gravity of the Clubhead. Hinging controls the Club Face by rotating the Primary Lever around one of three Hinge Axes; Vertical, Horizontal, or Angled. Release Interval, Stroke Length effect Clubhead Speed.

So, though one Hinge may appear to have more Clubhead travel than another because of how the #3 Accumulator is used (Right Elbow Path through the Release Interval), the Sweet-spot has the same Travel. Meaning that from start-up to Finish, the Clubhead Travels the same distance regardless of Hinge Action.
