Wilson Staff Di9 Irons: Wow. Get on the green, baby, come on. Powerful Iron. It's a good-looking club. The striker was amazingly comfortable. It's a meaty looking machine. I could hit shots here all day. Introducing the all new, all powerful Di9. Built on a platform of raw power. Inherited from the award winning Di7, the new Di9 takes distance to a whole new level. By using a more toe-friendly cavity design, we've widened the sweet spot. It also results in the highest MOI of any iron that we've produced. Right in the sweet spot, dead solid, perfect. Incorporating a soft urethane insert into the heel of the club widens the sweet spot even further. When I look at it, I see forgiveness. Oh, cut that bit at the toe. It works just the same . It also serves as a shock trap. They reduce the vibrations that travel through the head zone of the club into your hands. Very solid. I love how they feel. The Di9 includes Wilson's patented wide tip technology. This prevents twisting on off-center hits, and delivers more club head speed. Well, I hit it 180 into the wind, haven't I? Making me look good, these irons. There's nothing longer, there's nothing straighter on the market. The new Wilson Staff Di9 Irons. More power, more accuracy, more fun to play.
