Standard Face (157cc based on 3-wood) classic shape, stainless steel head, graphite shaft. Driving cavity on sole allows for greater distance and control, with a high, flat ball-flight. Balanced weight distribution in the perimeter creates more stability on heel/toe miss-hits and a wider sweet spot. Deeper Center of Gravity (CG) creates a penetrating ball flight with no balloon effect; ball is less apt to be affected by wind. CG is aligned with the ball at impact every time.
