This week's RBC Canadian Open isn't looking much different than a U.S. Open, considering Shaughnessy Golf & Country Club's three main obstacles: Narrow fairways, small greens and – the week's biggest topic of conversation – thick, tough rough.

"It's very penal," said Titleist Brand Ambassador Kris Blanks, the first-round leader at 3-under 67. "If you get it in play, you're able to attack. But for the most part, just try to keep everything in front of you. Hit a lot of greens and keep putting the ball."

Not a bad time to work with the Titleist Tour Team on dialing in your equipment. Here are are a few updates from the practice rounds:

 • Putting in some work on the range with his Titleist 910D3 9.5º driver (Mitsubishi Rayon Diamana 'ahina 72 shaft) on Tuesday, Titleist Brand Ambassador Jimmy Walker (pictured above) felt like he was hooking the ball a bit too easily. Titleist Tour Rep Jim Curran suggested Jimmy adjust the SureFit Tour hosel from A•2 (standard loft, +1.5º upright) to the flatter B•2 (standard loft, +.75º upright) setting. Jimmy preferred the resulting ball flight, and took that setup to the first tee Thursday.

Titleist Brand Ambassador Jarrod Lyle also made an adjustment to his Titleist 910D3 8.5º driver (Mitsubishi Rayon Diamana White 83 shaft), after noticing that it was leaking a bit right. Jarrod quickly clicked his SureFit Tour hosel from C•1 (-.75º loft, -.75º flat) over to D•4 (+.75º more loft, standard lie). He immediately liked the control and ball flight of that setup.

• One hundred players competing in this week's RBC Canadian Open are trusting Titleist golf balls for their success this week, more than six times the nearest competitor with 16 and more than all competitors combined.

• Titleist is also first in iron sets (45), including 16 sets of the new Prototype Titleist AP1, AP2, CB and MB (712 Series) irons; sand, lob and approach wedges (143); and putters (58).

Titleist Brand Ambassador Brendan Steele was looking for a higher bounce with his 60º Vokey Design Spin Milled wedge. Brendan worked with several grinds this week: V, M and TVD. On Thursday, a new TVD60º (bent to 62º) was in the bag. (For more on all the Vokey Tour Grinds, click here.)

• One of our newest Titleist Brand Ambassadors, Morgan Hoffmann, was concerned that his Scotty Cameron Newport 1.5 Studio Style putter had been bent in the hosel. While the team was re-shafting the putter and dialing it into his specs, Morgan experimented with a Scotty Cameron Newport SS Prototype with a deep-milled face and a Tour Black finish. In fact, he was rolling his Pro V1x golf ball so well with it that he put it in the bag in Round 1.
