(5) It actually can't be bought or gifted. It's awarded to the CC that wins the clash for them to give to one of their members.
It can, though !
I know of one player who actually bought it on a whim, a second one commented in the shop that he had done so.
One shows another putter now, the other still sports the CC Max, but he has retired from the game, obviously.
IIRC, Mag got one from WGT for a review, and I remember him saying that there are better putters around.
That said, it looks like a big carrot for the Clashes to me, a Golden Calf as a pinnacle of the whole dreaded "a lot of money for nothing" CC XP thing.
