RB 566V
A three-piece ionomer (durable, firm cover) ball with the signature 566 micro-dimple pattern (tiny dimples that extend hang time) that bridges budget and tour-level performance with elevated launch, enhanced spin control, and forgiving flight characteristics.
What do these specs mean?
Compression
How soft the ball feels. Lower numbers (70–80) compress easier and help slower swings get distance. Higher (90+) rewards faster swings.
Cover
Surlyn is tough and cheap — great for distance and durability. Urethane is softer and grips wedges for more spin around the green.
Layers
2-piece: simple, long, straight. 3-piece and 4-piece add layers for more feel and spin control on approach shots.
Trajectory
How high the ball flies. Low = flatter flight with more roll. High = peaks up and lands soft. Mid = balanced.
Spin
Low spin = straighter shots, less curve, more roll. High spin = more control and stopping power on the green (but also magnifies slices/hooks).
Tier
Price bucket. Value = budget-friendly distance balls. Mid = solid all-around. Premium = tour-level spin and feel, costs more per dozen.
Best For
Try a sleeve first — ~$5 for 3 balls before committing to a dozen.

Who It’s For
The Mizuno RB 566V is built for slower swing speeds (under ~95 mph). It suits golfers who prioritize mid-to-high handicap, slow swing speed, all conditions, soft feel. In the Mizuno lineup, the RB 566V sits softer than the Mizuno RB Max.
Feel
With a compression of 60 and a ionomer cover, feel is noticeably soft off the face — marshmallow at impact, quiet off the putter.
Spin Profile
Expect balanced driver spin — neither squirrelly in the wind nor knuckling short. Around the green, the cover gives you workmanlike short-game spin — not tour-grade, but dependable for chips and pitches.
Trajectory & Construction
A high-launching ball — better for golfers who struggle to get the ball up or want maximum carry. The 3-piece construction uses a three-piece design — one mantle layer manages driver spin while the cover handles wedge grip. Performs well in cooler temperatures.
Price & Value
At $29.99 per dozen, the RB 566V is a value pick. Expect distance and durability over tour-grade wedge spin.
Buy it if
- Your swing speed is under ~95 mph and you want a ball that actually compresses.
- You play a lot of shoulder-season or cold-weather golf.
- You lose more than a sleeve a round and don’t want to grimace every time.
Skip it if
- You swing over 105 mph — you’ll overcompress the core and lose carry.
- You score in the 70s and greenside spin is your scoring advantage.
