The XR Pro driver's compact head will appeal to better players For what it’s worth, the XR Pro (set to 12 degrees neutral and paired with the stiff- flex Project X LZ Pro) was an absolute beast in testing. While it does seem like the standard model, with it’s recipe of high launch and high spin, appears well-suited for mid-to-high handicappers or for players that don’t generate high swing speeds, it’s worth noting that Stenson paired his existing Oban Kiyoshi Tour Blue 60 shaft with the standard XR head and he’s certainly not complaining. The only knock I have on the standard XR driver are varied results from shot-to-shot which may have had to do as much with the regular flex Project X LZ shaft than with anything related to the head. My launch numbers revealed a consistent 6 mph of additional club head speed when compared to my gamer and my longest drive flew 16 yards longer than any shot struck with either my current club or the Callway XR Pro. In Callaway’s recent advertisements for the XR, the company claims that their driver will generate up to 5 miles per hour of additional ball speed. Instead of a Speed Step Crown, the XR Pro driver has what Callaway calls a Forged Composite Crown. XR Pro is more workable and features a cleaner look (no alignment aids on the crown). Smaller, compact head shape (440cc) replaces the larger, more aggressively-designed head on the standard model. Callaway's Speed Step Crown improves club head speed By comparison, the XR Pro driver has a few important differences that are designed to appeal to more accomplished players without negating performance benefits golfers are looking for in a club engineered for speed. Maximum Shaft Load: the lightweight (50-gram) Project X LZ shaft at 46 inches long is engineered to deliver greater clubhead speed and produce maximum shaft load on the way down for greater energy transfer into the ball. The OptiFit adjustable hosel has eight different loft and lie settings to fine-tune your launch conditions. Speed Step Crown is a geometric feature towards the front of the crown which, when combined with the aerodynamic head shape, helps reduce drag and significantly improves club head speed.
