Callaway XR Deep Fairway Wood In the Callaway XR Deep Fairway Wood, Callaway started from scratch and changed everything from the Face Cup to the head shape to make golfers longer than they already are. Its led by the next-generation Forged Hyper Speed Face Cup that increases ball speeds across the face for greater distance and forgiveness, especially when you use it off the tee. More distance, lower spin, and versatility are the highlights of adding a re-engineered Internal Standing Wave, and the completely redesigned shape is suited to deliver higher speeds. Callaway put in all this technology so you can pick up more yards off the tee and the fairway. Higher Ball Speed and Forgiveness Across the Face Callaway developed a lighter, thinner, next generation of the Forged Hyper Speed Face Cup. It increases ball speed all across the face and makes this fairway wood easier to hit with more forgiveness. More Distance and Versatility Off the Tee A lower center of gravity (CG), a lot less spin, and even more ball speed are what we get when we move the weight low and more forward with the re-engineered Internal Standing Wave. Its an important piece to add distance, particularly off the tee and from the fairway. Completely Redesigned Head Shape The progressive face height and deeper face are designed to be used off the tee. Speed from Maximum Shaft Load The shaft is a key component to speed, thats why Callaway put in the new Project X LZ. It produces maximum shaft load during the downswing for greater energy transfer to the ball.
