body tilt will vary based on pitch location but the idea is that to transfer the most power you want as close to a 90 degree angle between the lead arm and the torso as you can get.
JJ, just so that I can be sure of 90 degree angle do you have a pic? I am sure Bass does.
Thanks.
take a look at that link Mark posted. it has some good images with markups.
Not sure I follow you. Do 1 through 8 address your question? Analysis
Sorry if my response is not on your point.
