The Srixon Z-TI driver uses Srixon’s centre of gravity technology in the WS System which combines Weight Optimization with Shock Absorption, to give more distance, greater accuracy and better feel. The 460cc Srixon Z-TI Driver uses the WS System with tungsten nickel weights and 0.5mm crown to achieve maximum distance with high launch and low spin. The weights are placed in differing positions in the head depending on the loft of the club, to create squarer impact and hence greater accuracy. The addition of the shock absorbing material and sound rib structure ensure both an excellent feel and sound.
