The nice thing about continuing down a specific technological path is that with each iteration you learn how to use it to greater effect. This iron is evidence of that. Learning from its work on its D7 iron, Wilson refined several of its technologies for use in the D9. For several years the company used a series of slots in the sole called “power holes”—polymer-filled cutouts along the sole that contribute to the flexing of the face at impact. A new iteration of powerholes was developed through a computerized shape-and-size optimization process to maximize ball speed and forgiveness across the face. Wilson’s designers looked at the trade-off between forgiveness and center-of-gravity location. In the D7, the choice was moment of inertia to mitigate the loss of speed on mis-hits, but lowering the CG height to help get the ball up took precedence here, which required moving weight from the perimeter to lower in the clubhead. The face is still a stamped stainless steel, but how it is welded to the body is significantly different. Instead of being welded entirely on the perimeter of the face, on the D9 it is welded to the outside surfaces of the topline and toe areas, leading to more rebound. Read more >>

Impact is soft and mellow, but the ball carries with a high, driving flight. The black-and-gold color scheme is elegant and cool.
I like the classic look of an iron that is just bigger than a blade. The sound of ball striking club was nice. Performed well shot after shot.
I liked the way these sounded. The ball compressed off the face and stayed online with a nice ball flight toward its target.
