The 2006 Callaway FT hybrid combines multiple material to optimize weight properties to give you better launch conditions and performance. The FT hybrid has a light composite crown, stainless steel face and body and a tungsten infused sole plate. This moves the Center of Gravity low to increase launch angles and provide better results on shots hit low on the face compared to higher CG clubs. This weight distribution also increases the Moment of Inertia to up the forgiveness factor of the club, making these hybrids a perfect replacement for those difficult to hit long irons.
