there are a number of differences between swinging & hitting & i'm only somewhat clear on the ones that influence the downswing, but address position isn't a defining characteristic as far as i'm aware, though you could well be right that hitters more often tend to start from impact fix

You've got it Tim. Very few absolutes, there are a few, or three to be exact, and three more that you should strive towards, everything else is pretty much wide open...

The lists in chapter 11 help you understand what goes together well, and what shouldn't be combined, although it's not exactly black and white, and chapter 13 gives you a pretty wide overview while letting you know the importance of separating dragging and driving, at least the way I read it...
