The Grease Monkey Pow is in Radical's EZ Use line of bowling balls. This ball offers more hook on medium-heavy oil conditions which is an expansion of ball motion for this performance line. Just like the original Grease Monkey, this ball features a symmetric core and Radical's innovative finger scoop technology. These features combined with a more powerful reactive coverstock produce a more aggressive hook. The features of this ball and it's value price will make you say POW! (or wow).
