Lets say you were in the final round of your club champs, and you had a simple bread and butter drive you need to hit long and straight. Are you saying you might Swing or Hit that shot depending purely on how you feel that day -- as opposed to any mechanical reasons such as "I usually hit it further with Swinging" or "I usually hit it straighter with Hitting"?
With everything on the line...
Hitting or Swinging...
I would 'Drag my Wet Mop' -- sustain Clubhead Lag -- from the Top through Follow-Through to as far as I could into the Finish.
