The new Wilson Staff NC9 irons incorporate the most advanced level of precision engineering and scientific research to deliver unparalleled performance for the technology loving golfer. The Staff NC9’s feature Wilson’s new double face technology and multi-piece construction, giving them one of the largest sweet spots on the market and ensuring maximum energy transfer from the club to the ball. The double face technology is delivered through a revolutionary welding process that fuses Titanium to stainless steel through a controlled explosion and gives the NC9 irons an optimum combination of high ball speeds and soft feel. Meanwhile the clubs multi-piece construction optimises internal weight distribution to maximise MOI and impact stability. This is increased by four unique weight distribution screws on the back of the club, the composition of which changes through the set to make the longer irons more playable, whilst providing maneuverability in the shorter clubs, meaning the Wilson Staff NC9s deliver on every front for every golfer.
