The characteristics you have defined are consistent with Hitting. In fact, no characteristic you mentioned is consistent with Swinging. Therefore...
Or at least enough of a duck to warrant the assumption!

For Swingers -- who Pull the Club through Impact -- Centrifugal Force powers the Secondary Lever Assembly only (the Golf Club), and the Shaft acts like a Rope.
For Hitters -- who Push the Club through Impact -- Muscular Thrust powers the entirePrimary Lever Assembly (Left Arm and Club) and the Shaft acts like an Axe Handle.
