The RZN Black is one of four models of Nike’s new tour performance balls, each one of which is configured for a different swing. The “Black” is designed for higher-moderate swing speeds and offers lower-spin distance. The core is a lightweight resin (thus, RZN), which allows Nike to create higher perimeter weighting with heavier outer layers. It’s an interesting idea.
The RZN Black seems like the ball I need. Ball trackers have shown that I get too much spin, which costs me distance. A low spin ball is the key.
