“D” is for distance as far as Wilson Golf engineers are concerned. And they have been looking to nurture as much of that performance attribute as possible from its Di iron franchise, which the equipment manufacturer first introduced in 2005. Their latest effort in that realm is the Di11, and officials say that fifth-generation product is longer – and straighter – than any of the others.
For starters, Wilson clubmakers developed a modified exoskeleton that pulls weight low (to promote a higher and longer ball flight) and back away from the face of the club (for greater head stability). The resulting ultra-wide sole is designed to offer improved turf interaction, whether on tight fairway lies or out of the heaviest rough.
In addition, the company looked to create a sweet spot with its Di11 that is as much as 36-percent larger than offerings by the four leading brands in the super game-improvement category.
Part of that comes from the removal of weight from the perimeter of the clubface and from inside the cavity. But it is also the result of discarding the urethane medallion it had employed in its Di9 model and replacing it with a coating of a lighter-weight elastomer coating. That not only allowed designers to re-position that all-important CG (Center of Gravity) but also dampen vibration. And by combining those advances with its wide tip shaft that enhances stability and improves forgiveness, even on off-center hits.
Another way that Wilson has boosted the distance performance of its latest iteration of its Di irons with the use of lightweight shaft options, in both steel and graphite. Those allow golfers to achieve higher clubhead speeds, which theoretically translate into greater length.
In addition, Wilson is offering its Di11 with a patent-pending half-and-half shaft, a technology combining graphite and steel that was applied with great success in high-performance baseball bats. The upper part of the so-called HNH shaft is graphite from the grip to the midsection, which removes weight from that part of the iron and dampens vibration. Then, steel is employed from the midsection through the tip, providing lower torque for more consistent shots.
