I have just purchased the Callaway Steelhead XR Pro with KBS Tour 90 Shafts. I was hitting the Callaway X20 Tours with Project X shafts which were about 9 years old. I found the visual set up to be about the same, just the right size head that creates confidence. The weight and feel was just outstanding, the ball just shot off the face and every shot has been mostly down the middle. They have expanded the hitting area, but keep the same great look on the face. I have actually gained 10 to 15 yards with these clubs. As I have gotten older I was losing some distance and now I have regained my youth. Thank you for the engineering detail you put into these outstanding clubs!
