I've got an Atomic Charge, pin just below the ring finger, and the cg kicked out to the right a bit, maybe 4-430 in relation to the pin. Small weighthole to bring the ball back to legal. First off, let me say that this ball flat out hooks. I normally throw in the 17-19mph range, depending on the condition, with above average hand. I also have Recharge, and this ball rolls a little earlier, but is stronger overall. My recharge is more skid/flip. I found the reaction with the box finish a little touchy, so I put a nice coat of polish on the ball. Ball gets down the lane a little cleaner now, with much more pop on the backend, and its much more of a consistent reaction for me. Hitting power is excellent as well. This ball reminds me a lot of the Flash Force, just a lot stronger.
