AMF uses a numeric rating system designed to differentiate our coverstock strengths. F10 least aggressive - F90 most aggressive. Note: Core dynamics must be taken into account with shell strength when selecting equipment.


Vintage AMF takes the next step in performance in a big way!! The Sumo SE will deliver big hook and bone crushing power. The F80 Solid coverstock will grip the lane without hesitation. Use the Sumo with confidence on medium to heavy oil conditions.
