Titleist Brand Ambassador Rory McIlroy takes a quick break during a chilly early-morning range session.

Rory's putter has "soft ski pole" shaft you would normally find in a belly-style putter. He prefers the extra weight.

Manassero plays a Pro V1x golf ball; 910D2 9.5 driver (Graphite Design Tour AD DI 7, D•1 setting); 910F 13.5 fairway metal (True Temper Project X X7A3, B•1 setting); 910H 17.0 hybrid (True Temper Project X Hybrid XHC1, A•1 setting); and 910H 21.0 hybrid…

The adjustable dual-angle SFT hosel allows for 16 unique loft and lie combinations.

Titleist Brand Ambassador Robert Karlsson warms up on the range with his Titleist 910D3 9.5 driver with a Tour AD DI-6 shaft and his SFT hosel in the D•2 (-.75º less loft, +1.5º upright) position.

Titleist Brand Ambassador Matteo Manassero meets with the media after his first-round victory. Manassero, 17, became the youngest player to ever win a match at the WGC-Accenture Match Play Championship.

He also plays a TVD 58º M-grind with Project X 6.0 shaft.

As you can tell, this flatstick has seen its share of putts – and cups.
