The new Wilson Staff DXi fairway woods meet the demands of the game's best. After two years of working with Padraig Harrington to perfect these clubs, we're happy to announce a new line of fairway woods and hybrids with a heavy mass concentrated sole in combination with a sloped crown that keeps the center of gravity low for easy access to the ball and higher launch from the turf. 1. Large Radius Sole - Allows the head to sit flush on flat lies but allows manipulation on uneven terrain. Heavy sole mass keeps the CG low for easy access to ball and higher launch angle. 2. Variable Face Thickness - 3-Zone variable face thickness expands sweet spot towards heel and toe. 3. Aldila Voodoo VS7 S-Core Shaft - Aldila Voodoo VS7 S-Core Technology utilizes a high modulus carbon-fiber stabilization rib running down the length of the shaft which increases the strength/stiffness by 80% greater than conventional graphite.
