0811 X Gen4

Hybrid crown construction with titanium heel/toe plus aluminum-vapor-infused carbon-fibre centre saves crown mass for low-perimeter redistribution. The carbon fiber centre reduces mass in the top of the clubhead helping lower CG position, increase MOI, and optimize ball flight. The 3-port weight system allows back-weight forgiveness configuration with the heaviest weight at the rear. Tour-leaning low-spin head with moderate MOI — the chassis's chief brief is max-distance, not max stability. The XF Gen4 sibling carries higher MOI.

Independent commentary called the chassis the brand's max-distance product — manufacturer-billed as the low-spinning high-launching offering. Reviewer testing at 100mph club head speed measured 147.4mph ball speed and 282.7 yards total distance — outperformed category competitors of the era by 0.6mph in ball speed and two yards in carry distance. Aluminum-vapor carbon-fibre crown keeps mass low for ball-speed-friendly CG. Top-tier 2021 distance.

Strong tour-spec workability. Four loft options (7.5°, 9°, 10.5°, 12°) — broadest spread in the comparison set, including a tour-low 7.5° head. Three sole weight ports (heel, toe, rear) with full aftermarket gram range — a draw bias with weight in the heel, or a low-spin maximum-distance option with weight in the front port. Aggressively sloped crown lowers CG vs the face center — encourages shape-tuning. Tour-leaning low-spin character supports the shape-maker brief.

Reviewer testing called the impact "a gut-punch to the golf ball" — premium tactile signature. The chassis features a Honeycomb TPE insert that was initially designed for optimal CG but was discovered to provide unique sound and feel at impact — the catalyst for the chassis's tactile DNA. Industry reviewer testing rated the sound/feel/performance combination 9/10. Internal polymer core dampens vibrations for exceptional feel. Premium 2021 tactile response — engineering-driven.

The Honeycomb TPE insert tunes the acoustic — described as the catalyst for the chassis's sound and feel. Reviewer testing noted the chassis has corrected the sound issue significantly vs the predecessor (which had been criticised as hollow and like a metal baseball bat). Described as a great sounding driver. Premium tuned acoustic appropriate for the era.

Address profile reads as a whole new look in cosmetics and design vs predecessor — a signature two-tone crown with titanium heel/toe plus aluminum-vapor-sprayed carbon-fibre centre is functional and visually distinctive. Aggressively sloped crown reads modern tour-leaning. Industry reviewer testing rated the sound/feel/performance combination 9/10. Premium design language appropriate for the higher MSRP.
