where did you buy it?
jose iI want to know if my driver is real it has the authentication sticker half way under the grip. And the grip is kinda bumpy.
I've had people bring in their Titleist clubs to get worked on, say, to have their club(s) shortened. If I take off a 1/2"-1", and install the grip, sometimes the grip will slide over and cover up the authentication sticker a little. I'm not too sure about the grip being bumpy though.
Just make sure that you purchase all of your Titleist equipment through an authorized Titleist rep to guarantee you authentic Titleist gear.
