I love this driver, not sure why it was discontinued so quickly. It is very forgiving, you can hit nice and straight every time. The only thing that is kind of off about this driver is the sound it makes when it hits the ball
This is a great club that Callaway gave up on too soon. I have 3 of them--soft, regular and stiff shaft for different temperature and course conditions. I think the square head must have put some guys off, but that design basically ensures a straight, powerful shot because of the mass at the edges--essentially a huge sweet spot.
