I bought one Callaway FT-iZ of 13 degree drivers with a regular shaft. After all the hype I was anticipating extra distance. Well, the face is very closed, not good for a person that drives the ball straight or a slight draw. The sweet spot seems big and I hit it in the center on almost all of my shots.

Off center they were not very forgiving with a big loss of distance.
Callaway's Fusion Technology uses the principles of multi-material design to give the FT-iZ a winning combination of feel and performance combined with a stunning appearance. The body of the FT-iZ is made from woven carbon fibre which is placed between an aerospace-grade titanium clubface and a rear weight constructed from high density alloy.
This construction gives the Callaway FT-iZ polar weighting with the heavy face and rear weight localising weight at the front and back of the club with the rear weight acting as the power source. With 74% of the club's weight concentrate at the face and rear of the clubhead the FT-iZ delivers a very high Moment of Inertia (MOI) to promote straighter and more forgiving drives. This distribution of weight also places the Centre of Gravity low in the clubhead for the mix of ball speed and spin control that deliver excellent, long ball flight time and again.
