i just got a 16# gamebreaker last nite and shot 761 out of the box. alll i can say is what a ball!!! i dont have the exact specs, i do know its drilled agressive - pin is over ring, with a balance hole. this ball really hits and i mean hard. i usually play down and in, and i could with no problem, right around the 1st arrow. this ball comes back with so much energy, i was highly impressed.if you dont have one of these -- get one -- this ball is well worth the $ spent. i can honestly say with my "gamebreaker" and  "the one pearl" i cant wait to get back on the lanes, way to go ebonite!!!
