Wonton there are a number of factors that contribute to a big ole hook. It sounds like your ball position is fine. Do you slice the ball on a more than casual basis? I'm am thinking there two issues. I remember looking at your swings few months ago. You are striking the ball with an over the top shut club gave and/or the shaft is wrong for you. I think I'm remembering you as a hang back swinger. Which would cause this. I'd really get some eyes on your swing and work on the advise given if you do infancy get a lesson.
