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.

There is a new Cobra in town, boasting a lower RG and nearly twice the differential than its predecessor. The King Cobra features the traditional lightbulb core matched with our F55 coverstock to provide a smooth, continous motion on medium lane conditions.

The AMF King Cobra will be a great step up compared to the Cobra SE. The King Cobra will be slightly stronger than the Cobra SE. The King Cobra will be a smooth rolling ball due to the 4000 finish but still get decent length due to the Lightbulb shaped Weight Block. Look for this ball to be a great house shot killer and also handle some medium sport shot conditions.
