Lots of tour players and teaching pros preach a slightly open stance (in relation to the target) and hips and shoulders parallel to the target line. Jack Nicklaus and Fred Couples are two of them. You won't find any that suggest a closed stance angle is a good postion for a set-up (unless they're teaching a person to hit a draw by swinging along the target line). Get away from the closed stance because you'll develop the old two-sided miss... block fades or over the top pull hooks all day long.
