IMO: I think that is one reason Howard and Crystl's methods are so successful. How they teach the major components of the swing seem to inherently include maybe some of the smaller, fine tune characteristics as well.
Howard was gracious enough to share with me the Matrix drill and I have compared it to what my DDs hitting coach teaches her and I see a lot of similarities in hitting philosophy. His approach seems to take the mystery out of creating good hitting techniques and I do like what he says about the batter should "dance" with the pitcher.
The one criticism I have is that he continually makes reference to his belief that because the female body is different than males, that you have to modify your teachings based on the gender of the batter. Not sure I agree with that when you compare the set-up and swings of the best hitters in both baseball and softball, their seems to be an identical series of events that produce an efficient, repeatable, powerful swing that all good hitters share (regardless of whethet they are male or female).
