Callaway Men's XR Fairway Wood Higher Ball Speed And Forgiveness Across The Face We've developed a lighter, thinner next generation Forged Hyper Speed Face Cup; It makes the face up to 36% thinner to increase ball speed More Distance And Versatility For Any Shot A 20% lower CG, 200 rpm less spin and even more ball speed are what we get when we move the weight low and forward with our re-engineered Internal Standing Wave Completely Redesigned Head Shape You can see by the look of these clubs that they have flatter leading edges and a higher toe; The face height is shallower vs. X2 Hot for players who use these clubs mostly from the fairway Speed From Maximum Shaft Load The shaft is a key component to speed, that's why we put in the new Project X LZ; It produces maximum shaft load during the downswing for greater energy transfer to the ball It's not just speed, it's forgiveness, with a 16% larger sweet spot
