I just found what I think is the orginal ninja (black with splashes of either blue or purple). I am just wondering what type of reaction I should expect out of this. The ball looks like the polish was removed and the pin looks to be 2 inches. How would this ball compair to my black ice (drilled straight up, pin under and a blazing inferno drilled ring finger through pin). Would this fit in between the two, be stronger, equal or weaker than my current equipment,
Thanks
