The new T7 Quad Square Super MOI 460 driver features 4 movable weights that allow you to customize the club to fit your swing.  This provides you with the ability to customize the club head for optimal ball flight trajectory for increased distance with forgiveness with outstanding playability. The major advantage of this massive square club head is a greatly increased MOI that promotes tremendous forgiveness and consistent distance off the tee. The USGA has a new limit on MOI for this exact reason.
