• The square head increases the club head's Moment of Inertia (MOI) or reduced twisting during off-center hits.
• High MOI face keep the ball straight and long down the fairway!
• Squared face geometry enlarges the hitting area and increases forgiveness.
• Moving the center of gravity farther back raises the launch angle thereby making the clubface easier to square for straighter drives.
• Variable face thickness in the face, sole and back wall controls clubhead deformation for maximum energy transfer, reduced spin and high launch angle.

The Integra I-Drive Square fairway woods are at the vanguard of fairway wood technology. The I-Drive fairway wood's weight is moved further back and more towards the heel and toe, hence the square shape, to produce the most forgiving fairway wood head.  To understand this, it's important to understand Moment of Inertia (MOI). MOI is the term applied to how resistant the clubhead is to twisting when a ball is struck. For example, if your swing is a little off and you hit the ball on the toe of the clubhead, a clubhead with a higher MOI will twist less as a result of the mis-hit. This creates a better chance that the ball will still go where you intended and with less loss of distance. By moving the weight in the Integra I-Drive fairway woods to the rear of the head and to the heel & toe the MOI is significantly increased producing a head that testing has shown 8% - 10% improvement in accuracy on mis-hit shots.
