Relative to category peers · methodologyPros & cons
- Number one priority is forgiveness, not workability — purpose-built slow-swing forgiveness profile
- MOI on the same level as the forgiveness-spec sibling despite 50g lighter total weight (10g out of the head)
- Extensive loft range — 15°, 18°, 20°, 23° (3W through 9W) — most lofts in the 2021 line
- Reviewer-tested: 68.8mph swing produces 102.2mph ball speed, 14.6° launch — easy elevation for moderate swings
- Targeted only at moderate swing-speed players (under 90mph driver) — not a fit for mid/fast swings
- Workability is explicitly deprioritised — pancake profile + deep back-CG biases launch over shape control
- No movable-weight system — fixed back-CG architecture only
- Limited tour validation — slow-swing entry, not a head used by the brand's PGA Tour staff
