Nike 20XI, $46
IT'S FOR: Better players who benefit from a high-spin ball.
SKINNY: Top-of-the-line Tour model. It spins more than the 20XI X. The larger, softer resin [RZN] core contributes to a softer feel and a lower-pitched sound than last year's 20XI-S [while maintaining ball speeds off the driver]. A resin mantle [replaces urethane] reduces spin on iron shots by 300 to 400 rpm.
Nike 20XI X, $46
IT'S FOR: Better players who need a lower-spinning ball than the 20XI.
SKINNY: A slightly harder cover than in the 20XI delivers a firmer feel and less spin on scoring shots. The light resin [RZN] core and heavier outer layers create "perimeter weighting" for inflight stability. The core, and distribution of mass, combine for faster ball speeds [up to 3 mph more] than the old 20XI X.
Nike ONE RZN, $30
IT'S FOR: Aspiring players who seek a soft feel and added long-game distance but won't pay for a Tour ball.
SKINNY: The 3-piece ball features the same large RZN core that's in the 20XI, with minor alterations. The ball's rubber mantle reduces spin so players should hit straighter shots on a more consistent basis. The One RZN launches higher than 20XI with lower spin.
Nike ONE RZN X $30
IT'S FOR: All skill levels who want balanced performance with a slightly firmer feel.
SKINNY: The new larger, soft RZN core is tweaked a bit from the 20XI X. This 3-piece ball has a rubber mantle layer [20XI X has a resin mantle] and a Surlyn cover. A wide variety of players looking for max distance and a more penetrating trajectory would do well to check out the ONE RZN X.
