The Callaway FT i-Squareway wood not only has one of the most clever names for a golf club, but also has a high Moment of Inertia design. With the square design, discretionary weight is pushed to the corners that allows the club to resist twisting. This helps the ball maintain ball speed and line for off-center hits. Variable Fact Thickness allows the ball speeds to be faster and the sweet spot larger for optimal performance.
