Callaway FT-5 Driver
The Callaway FT-5 driver uses Fusion Technology to move discretionary weight around to produce different Center of Gravity configurations. The face of the club is at the limit for Characteristic Time, the measure of how "hot" it is, to give the fastest possible ball speed. The shape and weighting of the FT-5 increases the Moment of Inertia to reduce twisting at impact and thus increases forgiveness.
