I don't want to argue the point and It doesn't bother me if he Hit-Swung-Swat-Swit or nibbled on the ball, but are you using the glossary definitions included in the 6th Edition?
Maybe Hogan was a Switter?
Not for argument purposes . . . I'm actually not sure about it at this point . . . I just see some distinctly different shoulder motion from Hogan than others . . . HOw about this . .
Can you give us definitions and examples (pics maybe) of Flywheel motion vs. Backstop/Launching Pad?
Gotta get ready to burst out to work . . . but I'll chime in too.
