Ball Specs
Cover Stock: F80 Solid
Finish: 1500 Polish
Core: Sumo Symmetric
Layout: 65 x 5 1/8 x45
RG: 2.49
Differential: 0.050
Intermediate Diff: N/A

The new AMF Sumo with the F80 Solid Cover Stock and Sumo Symmetric Core is able to adapt on multiple lane patterns. My ball layout is 65x5 1/8x45. For a low to mid rev player this ball reads the mid lane very well and does not over react down lane. I tested this ball on THS 41 Feet and PBA Johnny Petraglia Pattern 36 Feet with great success. If you need ball thatís gives you a great look on multiple patterns, put the Sumo in your bag today!
