• The Vokey SM9 features a progressive centre of gravity (CG) on all lofts, which optimises the flight, accuracy and tolerance of the ball. • With tapered toplines and different hose lengths, the Vokey I+D team has increased the height of the CG to the highest loft, promoting a lower and more controlled flight. • The centre of gravity is also in front of the face, resulting in a higher MOI, exceptional feel and an embroidery side that simply wants to be quadrupled on impact. • The patented SM9 Spin Milled grooves are carefully engineered through a new cutting process to maximize impact and durability. • The micro slots are individually cut between the slots, maximising the effect on partial strikes. • A patented heat treatment is applied to the impact area that doubles the durability of the groove without compromising the feel, making it the golfs most durable groove.
