Performance index
Six researched ratings, lower (blue) through to elite (gold).
Where it wins
- Feel78
- Sound78
- Forgiveness77
Watch
Rated highest for feel and sound; its softest dimension is workability.
You're a mid-to-high handicapper drawn to one repeatable swing for every iron, and want maximum distance and forgiveness.
You strike variable-length irons well, want to shape shots, or find the short irons play too long — the standard SpeedZone fits better.
Pros
- Exceptional forgiveness with one repeatable swing for every iron
- Long and high-launching for a mid-to-high handicapper
- Cobra leads the single-length category
Cons
- One length is a commitment — the short irons play long and gap wider
- Divisive looks and a harsh feel on a mishit
- Low spin and a flatter landing can struggle to hold a firm green
By dimension
Forgiveness
StrongVery forgiving and consistent — the same low-weighted, heel-toe SpeedZone head, with one repeatable length steadying every strike.
Distance
StrongLong, if behind the standard — long irons play shorter at 7-iron length, though a big-sweet-spot PWRSHELL face keeps ball speed up.
Workability
ModestOne length is about consistency, not shaping — a big, offset, strong-lofted head flies high and straight, holding one line.
Feel
StrongThe same firm-but-damped strike as the standard SpeedZone — a medallion quiets a thin cast face, though a mishit feels harsh.
Sound
StrongA moderate crack at impact — the medallion damps a thin cast face, but it stays livelier and louder than a forging.
Looks at address
StrongThe same divisive head — a carbon-fibre top line and bright chrome that read high-tech to some, distracting to others.
