My first round went very well (Wensum Valley, Norfolk) I manage to finnish all 18th holes just under 100 marks! Fluke...may be?

The question here is What is the best postion when you are Tee-off? I have my left leg nearly in line with the ball but when I watched the open on TV, many pro seem to have the ball right in the middle of the legs! (like iron swing)

Am I doing the right thing? or the Pro are so good, they can stand in whatever position that more comforthable to them?

Thank you
