Srixon Z-RW Titanium Driver. New for 2008 the Z-RW Driver features a curving projection sole, that for every loft option provides the technology to suit golfers of all abilities. The 460cc driver's new power weighting system, 2.8g of tungsten nickel, ideally positions the centre of gravity for lower spin and a higher launch. It's 4 zone face design controls hook & slice side spin gathering the ball towards the centre, while the starburst t power face ensures a uniformed consistent hot launch off the enlarged sweet spot. The Fujikura SV 3014 shaft is tuned to get the best out of the head and deliver this low rate spin ratio so the ball can travel better
In the lower lofts the periphial weighting sits towards the heel to help with trajectory and shot shaping, while in the higher lofts the weight is moved around to promote a straighter shot with less slice and hook spin.
The 4 zone face design - where the bulge and roll of the face differs in 4 different zones - of the Srixon Z-RW Driver also helps reduce the severity of bad shots by enlarging the sweet spot
