ST-Z 220

Independent robot testing measured forgiveness at 89.3/100 — the most forgiving driver in 2022, ahead of category benchmarks. The new 20g stainless steel weight in the rear-centre plus expanded carbon-composite sections on sole/crown produce more consistent launch conditions all over the face. The chassis Sweet Area is 20% larger than the predecessor. Top-of-test 2022 forgiveness — the gold standard.

Reviewer launch-monitor testing measured 147mph average ball speed at 102mph swing speed with 2,572rpm spin in the 9.5° head — ball speed competitive with category leaders. But independent robot testing distance score was 85.5, falling out of the 2022 top 15 — the chassis trades raw distance for forgiveness leadership. Spin went up vs the predecessor (2,020 → 2,572rpm), trimming the top-end yardage. Solid but no longer category-leading.

The head sets up square to slightly open geared toward the more skilled golfer who wants to hit a long, straight bomb rather than shaping their shot. Engineered for straight-line low-spinning efficient ball flight. Hosel offers ±2° loft and up to 3° upright lie adjustments. Single fixed 20g rear-centre weight — no shape-tuning hardware. Better players can manipulate via swing/setup; the chassis defaults heavily to neutral.

Reviewer testing called the head "outstanding" on feel — more dense feedback than competitors, sitting between muted and crisp profiles with a lively impact sound. Independent robot testing reported the chassis was "one of the most well-liked drivers for both looks and feel" in the 2022 panel. Harmonic Impact Research and HIT-tuned internal sound ribs tune vibration for a tour-correct profile. Best-in-class 2022 feel.

Acoustic profile reads fantastic at impact — medium in pitch and fairly quiet. Misses are easily differentiated from pure strikes in both feel and sound, but mishits aren't harsh or unpleasant. HIT-tuned Impact Sound technology with internal sound ribs fine-tunes the sound to an appropriate frequency, and Harmonic Impact Research refined the acoustic further. Mid-pack with the 2022 family's pleasing muted thump.

Industry panel testing called the head "one of the most well-liked drivers for both looks and feel." The 460cc head volume is pushed slightly lower to the ground and sets up square to slightly open — tour-leaning at address but still confidence-inspiring. Expanded carbon-composite sections on sole and crown clean up the silhouette. Premium design language with visible carbon weave.
