Shawn, another way to think of it is the handle of the slingshot is the rear leg. Stretch behind the handle. Sudden barrel turn (and by sudden I mean more sudden than most will ever know. It takes practice and your forearms will hate you) releases the slingshot. The handle (leg) will snap/turn forward once the resistance against the leg is gone. You are not trying to rotate your spine. The feeling is very direct and towards the opposite field which happens to be inline with the stretch behind leg. But the rear leg will turn the turning barrel into the ball. Believing the front side is the handle will never allow you to drive the ball oppo field bc you have to rotate and/or push your barrel to the ball.
Understanding the feeling in this clip may change your mind more than my words
Could you post the single best explanation by TM(I think this is where this is all from if Im not mistaken) of how this works please? Ive seen a few, but Im not up to date with the specifics.
I like the idea and think it helps a lot of hitters. But for some different reasons maybe.
