The Callaway X Tour fairway wood is made to have improved turf interaction, more accurate alignment and a mid to low ball flight. The X-sole design causes the club to rest on two raised portions of the sole. This prevents the club from rocking so you know that your line is correct. The weight of the club is distributed around the perimeter to increase forgiveness to keep your ball online, reducing side spin. Add that to the Variable Face Thickness, and you get a longer, straighter fairway wood. The Tour version of the club has a slightly smaller head and stronger lofts.
