Srixon Z-Ti Titanium Driver. New for 2007, the Srixon Z-Ti Titanium is the new conforming 460cc titanium driver from Srixon. High launch and low spin is generated by a tungsten-nickel weight and a thin 0.5mm crown. Weights placed at different positions in the head, depending on the loft, promote a squarer impact and greater accuracy, working in tandem with a newly designed solid impact power face. Shock-absorbing material and sound rib structure ensures excellent feel and sound
