AMF Pure

AMF Pure Bowling BallThe Pure™ creates the most overall hook of any ball in the AMF300 line, past or present. This is achieved through four factors. The first being the F90™ coverstock, our most aggressive in the line today. The second part is our NEAT "E" (1,500 grit) typography finishing system, which creates the most uniform surface used in the industry, and provides the teeth needed for the wettest conditions. The Combustion™ symmetric core makes up the third part of this foursome, with a medium RG 2.51 and high Differential .054 engine, designed to create a motion you can count on, shot after shot. The final factor is you, so go ahead and throw it PURE!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.
