Independent testing confirms MOI around 9,700 g·cm² — just below 10K to preserve adjustability. Spin variation reduced up to 50% on parts of the face versus the predecessor thanks to new roll radius. Spin zone-spread dropped from 703 rpm to 404 rpm — a 64% R² reduction means vertical strike location went from dominant factor to secondary. 96.2% playable rate at slow speeds. Manufacturing breakthrough: robotic face machining means every head is identical (versus predecessor hand-grinding inconsistency).

Robot testing noted the head gives up about 4 yards of total distance compared to the standard sibling — the conscious trade-off for higher MOI and consistency. Independent launch monitor testing at 95-105 mph produced ball speeds 140-155 mph with good shots spinning around 2,500 rpm and shots low on the face jumping just 200 rpm. Distance spread tightened from 26 yards to 20 yards. Solid distance for the forgiveness profile but trails the standard, low-spin, and dedicated 10K-MOI competitors.

Major upgrade over the predecessor which had no movable weights — the head adds two flippable TAS ports (13g + 4g) enabling real spin/launch/forgiveness changes. The head remains mildly draw-biased with the deepest CG in the family — limited two-way shape capability but better than the predecessor. Designed for golfers who want straight ball flight with launch help; not a shot-shaper's tool. The added adjustability lifts workability meaningfully versus the predecessor baseline.

Reviewers note the head is just as responsive off the face in terms of feel as the predecessor, but with some added softness and depth — one publication titled its review asking whether this is the best-feeling driver in golf. Consistency of feel across the face is exceptional with excellent stability in mis-hit areas. Acoustic sole ribs and composite crown bridge reduce unwanted vibrations. Top-quartile feel — the added softness and depth over the predecessor is the key refinement.

Reviewers describe a medium-pitched, percussive crack that sits brilliantly in the middle ground, avoiding both high-pitched tinniness and dull thud. The acoustic feels and sounds confidence-building at address. More muted, solid sensation is refined via composite crown bridge and acoustic sole ribs. Some reviewers note it sounds a bit on the thin, hollow side compared to recent competitor releases. Strong sound for the 2026 class — meaningful refinement versus the predecessor.

Industry awards recognized the model at the top tier of the 2026 Hot List. Reviewers note the modern aerodynamic head shape provides a confidence-inspiring profile at address — stretched front-to-back versus the core model. The deepest CG in family means a deep/bulbous footprint at address — polarizing for better players but reassuring for the target high-handicap audience. Carbon crown finishing remains clean and matte.
