There is a device you can stick on the face of a club that is like a steel rod. I think it is a magnet. If the club is soled square, the rod will point straight. If you steeping the club, the rod tilts out to the right. This means that you will either need to swing this way and adjust the club's lie angle flatter OR change your swing to bring the club in shallower. Likewise, if you flatten the club, the rod titls out to the left. This means that you will either need to swing this way and adjust the club's lie and steeper OR change your swing to bring the club in shallower. The bottome line is that your club's lie angle need to match your plane angle at seperation. If not, you can make perfect swings all day and never start the ball on line.
