well having it at your side like a dana quigley will result in shorter swing wich could lead to less power, but should be easier to control. I say try it both ways and see if you hitt it straighter or farther with the different motions and then see wich seems more important to you with your game. I prefer to keep it to my side and allow my right elbow to bend right away then let the arm come off my side at the top then as i shif my weight left let it come back to my side.
