Thanks again, Bottle!
Thanks, again. You inspired me to check that Wikipedia reference and the Google search led me to the AnatomyZone.com youtube videos in addition to the Wikipedia discussion on the shoulder movements. Just a reminder for your readers here, scapular retraction = scapular adduction. But if you want a fuller understanding, you really should check out some of the videos on youtube. Damn, I can't believe how great it would be to be studying anatomy for the first time with all these visual aids that let you see everything in 3D and do immediate virtual dissection peeling away all the layers of muscle, etc. It was just 25 years ago, but we had to look at books and go to the labs and study cadavers and models. I imagine you can find just about anything on youtube. I'm a little puzzled I find time to look at anything else. There is so much to learn and so much information available for free. Of course, figuring out which is good information may be another matter.
But back to the kick serve. I'm not at all sure all this deep thought about anatomy is really going to help that much in developing your kick serve; probably just tie you up in knots. You are much better off trying Jeff Salzenstein's "Dirty Daiper" and kneeling serve drill, much as I think the underlying premise about the follow through and reduced internal rotation is fallacious; it's still a good drill. However, I understand that you love the intellectual challenge of visualizing a new approach and trying to execute what you have come up with.
You are largely correct that the difference is not so much in the arm action. It is more in the angle of attack at the last moment which changes the ball toss moving it slightly to the left. Don't overdue that or you can easily strain your back. But the new phrase I want you to start to focus on is "ulnar deviation". Even as the arm is going through largely the same motion on the second serve as the first, the wrist is firing on all cylinders in ulnar deviation to get a little extra spin to the side for an effective kick serve.
