Yeah. I have read some on it though and Phil's was designed for him. (not one you can buy of the shelf)Apparently he hits down on his driver more then most pro's, so Callaway repositioned the weight to give him the exact launch angle he wanted with his swing and allow him to continue to swing down on the driver. How cool would that be to go into their testing area and have the engineers with all their equipment specefically design the club for your swing.

You can not buy one like Phil's, I think they have several diferent weight distributions inside the club you can get. It is one of those types of clubs that you need to know your swing before you go out ad put down a lot of money.
