The Ninja SE is the latest in a series of retro remakes for AMF. Years ago, we got the Cobra SE and the Bull Whip SE, and more recently we got the Night Hawk SE. The new Ninja SE uses the low RG (2.48″) and high differential (0.054″) Shredder core surrounded by the F70 Solid reactive coverstock. It uses the NEAT finishing system and comes out of the box prepped with a T pad, which corresponds approximately to a roughness of 4000 grit.
This ball is deadly! The AMF Ninja SE is part of their Vintage line of bowling balls. This ball features the Shredder symmetric core that is covered with an F70 solid coverstock and is finished with AMF’s NEAT “T” 4000 grit pad. This combination provides a strong breakpoint motion with continuation and can handle heavier oiled lane conditions. This ball offers great entry angle with good overall hook.
