When I opened the Nike OZ 6 on Christmas Eve, I was surprised about the large head. I guess I was expecting a smaller head. The sight lines on the top of the head help immensely in lining up the putt to the target. The putter has good feel to it and has a nice sound when you strike the ball. The putter is face balanced. You can tell a lot of thought went in to making this putter. I would give it a solid four **** rating.
