Mizuno RB 566 — frequently asked
What is the compression of the Mizuno RB 566?
The Mizuno RB 566 has a compression rating of 65. 65 is on the lower end, which compresses fully on slower swings (under 90 mph driver). It is a good fit for high handicaps, seniors, and juniors who lose distance with firmer balls.
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?
Best fit is driver swing speed under about 90 mph. The 65-compression core fully deforms at slower speeds, so you keep ball speed and launch.
Does the Mizuno RB 566 spin a lot around the green?
No — the Ionomer cover gives less greenside spin than a urethane tour ball. It is built for distance and straight flight, not short-game stop power.
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.
Where is the cheapest place to buy the Mizuno RB 566?
Amazon is consistently the lowest sticker price for the RB 566, typically 10 to 20 percent below $28.00 MSRP once you factor in multi-dozen discounts. Pro shops and big-box retailers (PGA Tour Superstore, Dick's, Golf Galaxy) usually charge full retail unless they're running an end-of-season sale. Mizuno.com itself charges full MSRP but sometimes offers free personalization, which Amazon does not. Used / refurbished options on Lostgolfballs.com run 50 to 70 percent below new but ball condition varies.
