Product Details Di9 Distance Irons (Graphite Shaft)Greater accuracy. Improved feelAll new Di9has been delivered after learning a lot from Wilson Staff's award-winning Di7 iron . Distance superiority. Greater accuracy. Improved feel. The Di9 is more powerful, more accurate & more fun to play. Integrated Design. Generate maximum power. Stabilise the power for straighter flight. Reduce impact vibration for better feel.Low Profile, Wide SoleA lower profile & wider sole lowers the CG promoting a higher and straighter ball flight for greater distance.Stability, Speed and FeelWhile the wide tip controls twisting inherent in today’s oversized iron heads, the reduced weight generates maximum club head speed for even greater distance. This is the softest wide-tip shaft ever produced. Wilson’s patented wide-tip technology is applied to super lightweight shafts from UST and True Temper.Higher Ball SpeedComparative distance testing shows ball speed off of the Di9 to be superior, resulting in greater distance from a hot, responsive face. Bigger Sweet SpotWhile its low-profile, wide-sole head design is visually appealing, it is also highly functional. Because 85% of all shots are hit from the centre to the toe, the Di9 incorporates a toe-friendly cavity that extends the sweet spot to where most shots are hit. Highest MOIDi9 has the highest MOI when compared to key competitors.Wide-Tip StabilityA low profile head moves the centre of gravity (CG) down for higher ball flight. A wide sole moves the CG back for greater stability and a wider shaft tip reduces twisting on off-centre hits. Vibration DampeningCovering the entire length of the cavity is a low duro meter, vibration-dampening urethane medallion which expands the sweet spot to the entire length of the face. The urethane insert is thicker in the heel & serves as a shock-trap that reduces the vibrations that travel through the hosel, up the shaft and into your hands.New High Performance Grip TechnologyThe aggressive design on the fully functional grips have blister-free zones under thumbs and lower fore-finger. The vertical & horizontal grooves promote torsional traction for rotation. Shaft PropertiesThe all-new UST .370” Proforce V2 is designed with a softer tip section producing a higher launch angle, in a lightweight (65g) construction to deliver higher club head speeds. The Di9 Irons were awarded a Silver Medal in the Super Game Improvement Irons section of the Golf Digest 2009 Hot List. It was awarded this based on its playability, feel and looks. In Spring 2009, Today's Golfer magazine voted the Di9 Irons "Golf's Most Powerful Irons".
