Doom is right on about the code black, and the black ops. They roll almost identical for me. Though my code black is pin down, and my black ops is pin up. I tend to hit my black ops with 1000 pad and use it for heavy oil patterns. Ball really takes well to surface adjustments. Used black ops at nationals with 1000, ball worked great. Got me a 9 th place finish at the bowlers journal with it. So I would say ops is probably stronger, more versatile with its stronger solid cover. Both great pieces.
