The new 2008 Heater II fairway wood has moved the center of gravity lower and farther back producing a very high moment of inertia.  The high MOI allows the Heater II fairway wood to twist less on off center hits delivering straighter longer and more controlled shots.  The center of gravity has been allowed to be moved low and to the rear of the club face by the utilization of dual crown technology and triangulation the club head shape.  With this high MOI and very low CG this club head is a great match for golfers of all levels.
