The RBZ features an all new constant flex profile in the shaft resulting in a customized kick point.  Wherever pressure is applied on the shaft by the lower hand is where the stick will begin to load for a more powerful shot.  In a typical stick, the kick point is predetermined in the construction for a specific type of benefit such as a quick release.   As such, contrary to typical sticks, the RBZ adapts to your playing style to help achieve higher performance.
