Circle Hard Core 

Hard Coreâ„¢ represents the largest hooking ball introduced by Circle Athletics to date. This symmetrical core design and strong reactive coverstock perform very well on heavily oiled conditions and can be polished for medium oiled lanes. Lane Conditions Hard Core is designed for medium to heavy blend lane conditions. The 600 matte finish is best used in its "out of the box" condition for longer oil patterns. The Hard Core can be polished for additional length and backend reaction for use on medium conditions. While the Hard Core is not recommended for medium/dry lane conditions, the surface can be smoothed to a 1500 grit finish and polished for greater length and even stronger backend reaction.
