Overview
A better player chasing tour performance gets a four piece Mizuno ball with a urethane cover. A dual core firms up toward the edge, an ionomer mantle adds energy, and C-Dimples reduce drag in flight.
Soft urethane grips short irons and wedges, while the layered core supplies speed. The shared Tour and Tour X page is confusing, since the two are separate balls and the listing never says which one you receive.
Who it's for
Mid and low handicap players who want spin control around the green suit this ball. Newer golfers should save tour balls until they lose fewer.
Pros and cons
- Soft urethane cover for spin
- Four layer tour build
- Graduated dual core for speed
- C-Dimple reduces drag
- Version shipped not specified
- Compression not listed
- Wasted on slow swing speeds
Performance notes
Spin around the green comes from the soft urethane cover, while the dual core and ionomer mantle transfer energy for distance. The dimple design reduces drag so the ball holds speed through the air.
