The XCaliber Tour X graphite shafts were some of the best heavy graphite shafts ever made IMHO (they came in 85, 95 & 105). When I was testing shafts to put into my Sterlings, I liked the Tour X 95 MUCH better than the Recoil 95 or SteelFiber i95. They had better feel, better consistency, and they seemed more balanced. Too bad they stopped making them, and Golfworks have taken down all but the 105g Stiff from the website, and even those are showing as "backordered" so who knows if they'll actually be getting any more or not.
