lLead Arm on swing
Most of your info is good but I must disagree on straightening the lead arm at the beginning of the swing. If it is slightly bent you will have a shorter path to the ball and a more compact quicker swing also I saw no mention of the importance of keeping your hands inside the ball. Casting isn't good either it causes you to come around or hook the ball just let the ball get a little deeper on the outside pitch.
