Mizuno RB 566 — frequently asked
What is the compression of the Mizuno RB 566?

Is the Mizuno RB 566 a tour ball?
No. The RB 566 is a soft feel ball. It prioritizes distance and feel over greenside spin.
What swing speed is the Mizuno RB 566 best for?
A 65 compression rating does not establish one required driver speed. Use it as a relative feel reference, then compare the RB 566's cover, construction, flight and spin positioning; Mizuno positions this model for mid-to-high handicap players who want a high-flying soft ball at a value price. On-course or launch-monitor testing is the best final check.

The Ionomer cover generally emphasizes durability and a different feel/spin balance than a urethane tour ball. Mizuno positions this model around distance.
How much does the Mizuno RB 566 cost?
MSRP is $28.00 per dozen. That is a value-tier price — under half the cost of a premium tour ball.
