All 4 options feature Nike's latest Speedlock RZN Core, engineered for more distance, better feel and a more consistent ball flight. Both the RZN Platinum and RZN Black models are 4-piece balls targeted at betters players including Tour Professionals. The RZN Black is designed to spin slightly less (providing more accuracy/distance) than the Platinum ball which provides the best control/spin around the greens. The RZN Red and White models are both 3-piece balls designed to offer more distance. The RZN Red will carry a little longer, whereas the RZN White provides a softer feel for green-side control.
