By designing the shape of the head count to be able to deliver the best features required for each count, the center of gravity further depth # 3 - # design flow has been adopted by seven little deeper. # 3 will be up to directional stability at high moment of inertia design slightly larger head, # 5, # 7 was more open face angle (# 0.5 ° more open than 3) Holding a slender design and easy to just grab greatly improved the ease of operation and out of shape by employing head.

Was larger sweet spot in the direction of senior RBI "Star Burst Power Interface"

RBI's expert direction (vertical direction), an enlarged sweet spot on "Star Burst Power Face" by reducing the loss of vertical distance to be divided out RBI to manipulate the trajectory, distance is stable is obtained.

Large moment of inertia, raise the ball designed for ease of

High Power Weight-to-tungsten portion of the sole and heel portion (one 3.5gx 2) has been installed. This increases the moment of inertia, the direction has been achieved with less blur also depends on a stable, remove the core. Center of gravity lower than the previous model further depth and deep up the ball easier. 
Note: The weight fairway wood can be replaced.

Head design incorporating the views of the top professional and amateur
