Woods employs new Nike driver at World Challenge
Tiger Woods switched into a Nike VRS Covert 2.0 Tour driver (9.5 degree). Rory McIlroy uses the same driver in a different loft (8.5 degree).
Even bigger news from Woods, though, was his driver shaft. He went from a 73-gram Mitsubishi Diamana White Board to a 103-gram Blue Board.
Woods has used the 103-gram shaft in his fairway woods for years. The reason for the heavier driver shaft: Better accuracy.
