Our assessment of what constitutes good swing mechanics is so far apart that I see no basis for discussion.
As an example, you state, The hips rotate and supply a large amount of energy.....but they do not give it to the shoulders......they give it to the forearms. My position would say that the arms (including the forearm) are attached at the shoulders not at the hips. Energy can not just jump from the hips to the forearms. The energy from hip rotation must be transferred up the kinetic chain. This means that hip rotation aids the torso muscles in generating shoulder rotation, which is transferred through the arms, wrist and hands to the bat.
Our positions are very far apart. Do you see any basis for further discussion?
