Don't overthink this, this is very basic. Don't get confused by the words rotated or swinging or hitting, the question was regarding the pressure points location not it's action. For most a strong single action grip is by far the best choice and is mandatory in homers basic motion acquired motion and total motion curriculums. If you go to any tour event one thing that will stand out with nearly all their swings is their trigger finger grip with the first fleshy pad of the right index finger (pressure sensing pad) on the back of the shaft.
