Performance index
Six researched ratings, lower (blue) through to elite (gold).
Where it wins
- Feel87
- Looks87
- Sound86
Watch
Rated highest for feel and looks; its softest dimension is workability.
You want a stable, low-spin, neutral driver that flies straight and holds its line, from a wide range of swings.
You need built-in draw help (the ST-X), a lot of adjustability, or the very lowest spin for a fast swing.
Pros
- One of the most consistent, stable drivers of 2021 — a low-spin, neutral all-rounder
- A superb, solid feel with a tour-tuned muted sound
- A clean, neutral look that a wide range of players will get on with
Cons
- Low-spin — better for higher-spin players than for those who already flight it low
- Neutral and stability-first, with no movable weights
- Five seasons old, and beaten for outright ball speed by newer heads
By dimension
Forgiveness
SolidGenuinely stable — a deep, central weight and high MOI made it one of the steadiest, most consistent drivers of 2021.
Distance
StrongFast and low-spinning — an efficient, straight flight that holds its distance well, even off a shortish shaft.
Workability
ModestNeutral by design — it favours neither draw nor fade, but a good player can still nudge it either way.
Feel
ExcellentA wonderfully firm strike — heavy and forceful, with the dampened note Mizuno's tour staff wanted.
Sound
ExcellentA low, dampened note at impact — soft and strong rather than loud, dialled in for the better player's ear.
Looks at address
ExcellentA tidy, neutral head that sets up dead square — a shiny dark crown with exposed carbon that blends the up-to-date and the traditional.
