Going back to its D100, D200 and D300, Wilson ascribed to the ideology for its distance-enhancing drivers that lighter components can help golfers generate more clubhead speed. That, in turn, will help them achieve more distance. With the new Staff D9 driver, the Chicago-based brand is going after a significant market segment by offering a more traditionally weighted driver but giving it a new face technology that can deliver more yards off the tee.

In the past, engineers worked to determine which areas of the face should be thicker or thinner to produce the best performance, but they did something different in the Staff D9. They broke down the hitting area into hundreds of tiny regions and programmed computers to analyze each of those regions during simulated impacts. Wilson instructed the system to prioritize distance enhancement and ball-speed protection. Based on what the computer learned after each test, it made modifications and adjustments before running new simulations.

Wilson refers to it as PKR Face technology (peak kinetic response), and it likely will be a significant factor in Wilson’s wood designs for many years to come.

The result in the Staff D9 is a face that does not have symmetrical ovals or patterns on the interior but instead has tiny ridges and valleys in seemingly random spots. Wilson said it produces more ball speed when golfers hit the ball solidly and when they miss toward the heel and toe.

The Staff D9 driver also was made with a three-layer, carbon-fiber crown that saves a significant amount of weight and lowers the center of gravity. To drive the center of gravity farther down and back, away from the face, Wilson added a 10-gram weight to the back of the sole. That extra mass in the back of the head also increases the moment of inertia to help the club resist twisting on off-center hits more effectively.

For players who want a lighter driver, Wilson is making a 3-gram sole weight available.

Compared to its predecessor, the Staff D7 driver, the new Staff D9 has a lower profile and is larger from front to back, so it should be more stable. The D9 should produce about the same amount of spin and have the same peak height, but that apex should be achieved farther down the fairway.
