Callaway Golf Custom Shafted X-22 Tour Irons for 2009. Performance Irons Designed For Accomplished Golfers Seeking Premium Feel and Stability To improve on the highly successful X-20 Tour Irons, Callaway Golf engineers added new features that allow the X-22 Tour Irons to play even better and feel even softer. Precision Notch Weighting and a new sleeker hosel combine to raise the MOI for better stability and allow the CG to be moved lower and more in line with the center of the face. This generates ideal trajectories and significantly enhances the level of feel. THe head shape has been refined with the thinnest possible topline while still using 360-Degree Undercut Channel, and the optimized sole width progression provides better turf interaction. Precision Notch Weighting - Precisely positions more weight to the perimeter of the iron to create a higher MOI for greater forgiveness and stability while maintaining the CG position that produces ideal trajectories and feel. Tour-Proven Head Shape - Features the thinnest topline possible while still incorporating a 360-Degree Undercut Channel. The blade length is shorter and the CG has been moved lower and in line with the center of the face to provide unparalleled performance. Redesigned Hostel - The sleeker design significantly improves feel and allows the hosel to be more easily adjusted to fit a golfer's custom specifications. Callaway Golf Core Technologies - VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness; 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower and farther back in the clubhead, enlarging the hitting area and stabilizing the clubhead for more forgiveness. Sole Width Progression - The sole Width of each iron has been optimized based on the length and the loft to provide better turf interaction through the entire set.
