I believe bats are designed to be optimally swung about the knob.Can you explain how? Because I think I agree, but I'm not sure I could articulate it to a skeptic.
The best I can do is "You know how choking up real far takes away whip? This is the opposite of that."
The grip gives me a greater sense of the bat being whipped (felt in my hands into & through impact).
Here's how Busto's positioned the knob in her bottom-hand ... see lowest 'red arrow'.
