DJ and Rory are two of the best golfers in the world. Their records speak for themselves and they did not get to where they are by hitting high toe or low heel. Middle of the face baby, that's where the action is ! and that's where they make contact with the ball 9 out of 10 times so how can they justify a statement that the new M4 has helped them? I will bet that they are not even using the mas produced version of this head.

Curious as to how TM used swing data to design and market this club. There must be a ton of hacks out there.

Go and get yourself properly fitted, and I mean properly, take a few lessons to work on your swing path and you will be way further ahead of the game for less than the cost of an over hyped, over priced ( DJ,Tiger,Jason Rory and others don't come cheap) product.

The OEM's are desperate because of the limits set by the USGA on Drivers. Jail Break,Twist Face, please, give me a break.
