I doubt he is - he doesn't play a 5 wood, either. He plays a 9 wood bent to a seven. And I'm sure Cleveland ain't gonna tell Vijay to pack his bags if he won't play the HiBore XL...
He's playing the new HiBore XL Tour, should in store soon. There 2 versions. The std XL and a XL tour. The basic differences being that the std is deeper front to back while the Tour has a deeper face. The tour version is also 3 degrees open!!
he was using the plain ole Xl at the sony. It was on the survey for equipment they did there.
