The company that brought us the “Driver vs. Driver” reality TV show for amateur club designers has a little secret. Your clay models and napkin drawings and erector-set projects? They are nice, but if you want to really design a better driver, you need to think faster than any human possibly could, especially when you are trying to maximize ball speed across the face. The multiple-thickness-face design on the D9 was driven by artificial-intelligence algorithms that churned out more than 500 versions at a clip in search of the optimum pattern. Wilson’s process yielded a new face shape in which ball speed is faster not only for the best strikes but for the off-center hits, too. This performance improvement is good science, but the D9 works because it helps better players and slower swings alike. One design key is a weight-saving carbon-composite crown that helps lower the center of gravity while improving sound. The other difference-maker is a setup that converts the standard model to a 40-gram lighter version with a head that looks the same. Read more >>
Look / Sound / Feel
* Percentage of total score
Feel off the face is almost like a forged iron, but the ball still jumps. I saw really good spin-to-launch ratios. Easy and fun to hit.
That carbon-fiber look has become popular, and this take is pleasing without going too far. The sound is deep and powerful. My performance was consistent on best and worst hits.
Pure confidence in the soft feel. Hot off the face but barely notice contact because it’s so smooth.
