If you’re tall or short, and/or have an unusually shallow or steep swing, you may want to think about visiting JK's World of Golf, we can check whether the lie angle of your irons is appropriate. At the point of impact, if the head of the iron is too flat (i.e. the toe points down) it can drag on the grass, acts for an instant as a pivot, and causes the plane of the face to tile towards the right - which is where the ball will go. If the lie is too upright the opposite will occur.
