ST200

MOI measured ~4,800 g/cm² — nearly 15% greater than the predecessor via a new 11.6g back weight and compacted WAVE Sole. The chassis is characterised as the most balanced offering with high MOI and mid/low spin. Reviewer testing noted the head falls short of elite on both maximising ball speed on best strikes and preserving mediocre strikes — solid mid-pack 2020 forgiveness. SP700 Titanium face spreads ball speed across the strike zone.

Robot testing flagged the head as "a ball speed winner for mid swing speed players" with performance matching the best 2020 contenders including the TaylorMade SIM. Reviewer launch monitor testing measured 2mph ball speed gain at 100mph swing vs predecessor, with spin dropping from ~3,000rpm to ~2,700rpm. Today's Golfer recorded 8-yard carry gain and 14-yard total gain vs predecessor. SP700 / Beta Rich Forged Ti face (17% stronger than previous Ti) drives the speed improvements.

The chassis is the family's neutral middle option — single fixed 11.6g back weight, no shape-tuning hardware. The G stablemate is the tour-adjustable workable head; this one is built for neutral straight-line flight. Hosel offers ±2° loft and lie adjustments. Limited workability by design — the chassis brief is balance, not shape-making.

Mixed reviewer reactions. Reviewer testing called the feel a confidence-generating low-vibration response, while other testing found it "neither hot and explosive nor solid and satisfying" — "impact wasn't unpleasant, but it wasn't exciting either." The new Beta Rich Forged Ti face was a step up vs predecessor but lacks the dense-solid signature later generations achieved. Mid-tier feel.

Acoustic reads as a big "crack" — slightly above average in volume, medium in tone. Some reviewer testing noted a tinny character, although engineers worked hard for a tour-preferred acoustic. An external sound rib between the weight track and WAVE channel tunes the impact — without it, the forward-weight position would be too loud and clanky. Acceptable but inconsistent acoustic — predecessor of later refined ST230+ acoustic work.

Address profile reads as a pear-shaped 460cc with WAVE Sole and a 2g carbon crown — more compact WAVE geometry produces a clean, tour-leaning silhouette. Industry-panel testers reviewed the design favourably. The chassis carries the visual lineage forward from a 2019 predecessor that earned the brand's first PGA Tour driver win since 2000. Clean design language but pre-modern (no full carbon-composite crown panels yet).
