AMF Darkness Bowling Ball

The Darkness features the Dark Tower symmetric core with an enhanced flip block that provides a lower RG and higher Differential, perfect for a strong motion through the midlane on slicker conditions. 

The F77 Solid coverstock creates tremendous friction in the oil. 

Matched with a 4000 Abralon finish, the F77 shell provide massive overall hook without loosing anything through the pins. 

For best results us the Darkness on medium-heavy lane conditions. 

AMF uses a numeric rating system designed to differentiate our coverstock strengths. 

F10 least aggressive - F90 most aggressive.
