Took about 5 swing with the new Z yesterday and was not able to square the face at all, just massive blocks right. Not sure if it was the club, maybe it was me, who knows. I was just coming off some nice swings with a different driver so it was odd. On one hand I want to try again but on the other I kind of don't. The head looks great but there is nothing drawing me to it vs other options, and I say that as a Mizuno fan.
