i believe it's better to shoot with the ball towards the right side of your face (if right-handed). My reasoning is because your upper arm won't catch your chin. Also toward the right side will allow you to get more power. Just imagine if you are pushing a dumbell, we dont see people pushing up dumbell right in front of their face, it's alway a straight line from the shoulders. Now i'm not saying you should be shooting straight from your shoulder, because we need to align with our targeting system, aka the eyes. Imagine that the arm is the barrel and the eyes as the scope/targeting. The more aligned the two, the better, but we also need to mind the power for the shot. Which is why people stagger their feet so that the shoulder will be aligned closer to the eyes.
