To swing or to hit has always been a sore stop with me. I have read that to do both, Homer meant with different clubs, long=swing, short=hit. Others say the 4 barrel is both. I really don't know.
Here is something I recently posted on a question about Toms'swing.
It comes from Homers "notes" that will be part of the new edition of the "Book."
“...Left Arm or Right Arm - If the Right Arm Drive propels the Left Arm Lever Assemblies, it is still a Left Arm Stroke because the center of the Clubhead Arc is the Left Shoulder. It is merely Right Arm Powered. But - if the center of the Clubhead Arc is at the Right Elbow, then it is a true Right Arm Stroke, the Bat. Right Arm thrust can add considerable yardage for an out and out Swinger, provided its tendency toward Angled Hinging is recognized. Pivot Thrust can add about half as much increase in yardage for an out and out Hitter provided its tendency toward Horizontal Hinging is recognized.”
my other two cents then:
Then Swing is determined by shoulder position and Hit by right elbow. Too many swingers, on our hack level, are afraid to use the right forearm, thinking they are now hitters (god forbid) and Hitters are afraid of pivot. The pros use both correctly and this is how we see both Swing and Hit in our favorite swings. Don’t be afraid to use both halves of your body.
