Reviewer testing called the chassis very consistent in terms of both ball speed and direction with surprise at the forgiveness level for a players-only-style model. Independent commentary noted mis-hits feel so much like sweet-spot strikes that it doesn't provide much of an incentive to make better contact. Robot/lab data on the family: 15% tighter dispersion pattern on toe and heel strikes compared to previous models via Forged Aluminum Ring construction. Caveat — independent testing in real-world conditions noted giving up almost 30 yards on a bad strike — the 16g back weight (vs 24g in the family's max-MOI head) sacrifices some MOI for the tour-spec profile. Strong tour-spec forgiveness but the max-MOI sibling is materially better for off-center strikes.

Robot/lab data measured average ball speed 147.4 mph at 102.7 mph swing — top-tier 2021 efficiency. Independent commentary recorded 1-3 more mph of ball speed compared to the predecessor — meaningful generational gain. Reviewer testing confirmed low launch, low spin with penetrating shots and roll out — spin in the 2,200-2,500 rpm range and launch 11-13°. 250 rpm less spin than the family's max-MOI sibling; most forward CG and lowest spinning of the three family heads. Speed Injected Twist Face calibrated to the legal speed limit drives the speed gains.

Independent commentary called the chassis very workable and controllable with the ability to flight the driver practically any way you want — best workability in the family. Reviewer testing noted the address profile is compact with a slight pear shape — tour-leaning silhouette that frames shape-tuning. Low-spin forward-CG profile naturally rewards committed shape-shifting; 250 rpm less spin than the family's max-MOI head means the chassis responds to player input rather than imposing stability. The family's most workable head by design.

Reviewer testing called the feel unbelievably solid like driving a stake with a sledge hammer — feel makes the chassis addictive to hit and was declared a favorite driver feel of 2021. Independent commentary noted sweet-spot strikes feel and sound similar to the predecessor except impact is more crisp and a little more explosive. Forged Aluminum Ring construction acts as an acoustic skeleton, stiffening the chassis and delivering exceptional vibration dampening. Class-leading 2021 tactile signature.

Reviewer testing called the acoustic a mid-pitch crack that complements the feel well. Independent commentary noted the sound is more audible with a nicely balanced crack — meaningful generational acoustic upgrade vs the predecessor. Independent commentary on the family credited the brand's Acoustic Engineering with successfully replacing the harsh, metallic ping of older drivers with a muted, powerful crack via aluminum ring plus carbon crown resonance. Premium tour-spec acoustic for 2021.

Reviewer testing called the address profile compact with a slight pear shape — the chassis sits perfectly square at address in the neutral setting with black carbon fiber crown and thin band of white for alignment. Independent commentary confirmed it sets up square at address. Premium tour-leaning silhouette appropriate for the brief — visibly more compact than the family's max-MOI sibling which is longer front-to-back with a shallower face.
