My first move is a slight head move back to the right and up a bit, this keeps me feeling tall through the backswing. It also triggers the shoulders & arms to stay in a one piece motion away from the ball.
A great way to feel the movement you are looking for, is to set up as normal for you and lift the hole body trunk including arms hands so the club is just up above the ball. Then swing the club forward say about a foot and feel the balance of the club in the hands then make a backswing. Do this slow and smooth and you will feel the parts in your body that make your move first.
Now you know what moves first, be it arms or hands or shoulders, you can now make any slight change/feeling to a takeaway if required.
