For our new XR Pro Hybrids, we changed our whole approach to make a hybrid that's even longer and forgiving in a more compact head design for better players. From the ground up we developed a completely new upgrade to a Forged Hyper Speed Face Cup that increases ball speed across the face. We also put in more MOI and our lowest CG ever in a hybrid by positioning more weight lower and around the perimeter of the head. And we refined a way to lower CG even more, increase MOI even more and somehow, someway still free the face cup to flex for more ball speed too. It's amazing what you can do when you change everything.
