On to a short-game session with Titleist Brand Ambassador Michael Sim.

Michael carries two Vokey wedges: Vokey Design Spin Milled 54-12º and 60º (T grind) with Project X shafts.

Titleist Brand Ambassador Cameron Tringale puts in some bunker work while chatting with Titleist Tour Rep Jim Curran.

Titleist Brand Ambassador Ben Martin (left) shares a laugh or two with Scotty Cameron Tour Reps Larry Silveira (center) and Kelly Moser.

And here's how he marks his Titleist.

Scott plays a Titleist 910D3 8.5 driver with a Mitsubishi Diamana Blue 63 shaft.

Scott's three Vokey Design Spin Milled wedges are custom-stamped with "HI-YA": 256•10º, 60•E and 52•08º (True Temper Dynamic Gold).

And here's his Scotty Cameron Studio Select Tour Only Newport 2.7 putter.

That's Titleist Brand Ambassador Ryuji Imada.

Any guesses?
