Nike’s latest creation out of the oven is their revolutionary new golf balls. We don’t like to use the word revolutionary liberally over here only when a company really comes up with something remarkably different. Nike proved their case when they opted out of the traditional rubber core and added a Nike RZN (resin) core. The new core makes the construction easier with simpler layers allowing the ball to simply rely on the new technology of the center core. In practice these new golf balls helped gain more distance off the tee and give better control on the greens. Less spin but still great launch with good swing speed. Available in two different models: the 20Xi-S is for spin and control and the 20Xi-X is for distance and control.
