I am going to buy your video. How does what you teach compare to Mike Epstein and Preston Peavy.
Peavey (www.peavynet.com) advocates the full transfer method a combo of linear and rotational. He uses slow mo of Aaron and A-Rod that seems to show they are both linear and rotational.
Mike Epstein (http://www.mikeepsteinhitting.com/) seems to advocate strictly rotational.
