Tour Edge Exotics XLD Driver : Lightweight, sleek and strikingly distinctive: every last detail of the XLD exudes uncompromising power that reflects the Exotics name. The XLD s stealth-like geometric shape moves the head s CG (center of gravity) deeper and lower, generating an extremely high MOI (moment of inertia). A contributing factor to the XLD s performance is a laser-welded beta titanium face. The face is computer-milled and features varying face thickness from 2.8mm on the outer edges to 3.3mm in the center for explosive power. The distance generated by the XLD is nothing short of electrifying. Designed for the ultimate driving experience, in-depth research went into decreasing the XLD s overall weight. This led to extensive study on reducing wall and crown thickness and created one of the lightest drivers on the market. A new waxing process minimizes the thickness and weight of the titanium crown and allows more mass to be shifted to the rear corners of the head. With the XLD , overall weight is kept to a minimum. One of the lightest drivers ever designed, the XLD weighs in at only 295 grams and releases enormous club speed to produce dramatic distance gains.
