Remember that the position and alignments of the hands, pressure points, forearms and sweetspot are different in the loading action for hitters and swingers....7-3
Until you see, understand and can experience that bit...then you should not be thinking about release motions...
Once you understand the loading actions...then the release motions become easier to understand.
That is my opinion and experience of learning this stuff...
look under 7-3...there were some good threads on that with some photos that helped me.
