The Callaway Big Bertha Fusion Driver offers more forgiveness by raising the head's MOI measurement. More forgiveness means straighter ball flights, which in turn, means more distance. By changing the clubhead design to a more streamlined shape, Callaway has increased head speed so the club moves faster through the air. Reducing the weight and repositioning it in strategic areas optimize the center of gravity, increasing the MOI. Fusing the EXO-CAGE with triaxial carbon crown and sole allows for more weight in the perimeter and back of the clubhead for more forgiveness.
