New face curvature w/corrective face angle on off-center hits, to reduce side spin & deliver straighter shots. Provides more loft in high-toe & less loft in low-heel for more consistent spin. Hammerhead slot: the reinforced outer portions of the slot allow for a lighter, more flexible face, resulting in a larger sweet spot. The center portion of the slot increases ball speed low on the face and drops unwanted spin for more distance.
