This was probably one of the most hyped balls by Storm in a very long time. I drilled mine 55 x 5 x 45. What I saw with this ball was how the core really took over in the midlane. I find this ball is pretty clean in the front but man does it react to the midlane and continues in the back like a monster. I have to open my angles up a fair amount and use this ball as a later ball in league or tournaments. As usual with storm this ball is a monster when it hits the pins. This ball holds up to all the hype. This ball is a must.
