Actually, I thot that this was pretty clear - "Now, pragmatically, the best fit is long enough that you don't bash your nose. Why? Obviously that will accomdate the easiest gun mount and the greatest range of clothing. And more importantly it will bring the center of mass close to the rotational axis of your body and you will be able to turn faster."

But then that must depend on reading skills that all may not have.
