    Equipment Roundup: John Deere Classic

Tiger Woods hit only one driver en route to his 2006 Open Championship victory at Royal Liverpool. So it doesn't come as a surprise that players tested driving irons in preparation for the narrow, fast-running fairways they'll most likely face at Royal Liverpool.

TaylorMade's Ultimate Driving Iron was one of the biggest stories at the John Deere Classic. Six players had the driving iron in the bag at TPC Deere Run, including Chris Kirk, Davis Love III, Kevin Kisner and Troy Matteson.

Others testing the club included former Open Championship winner Stewart Cink, who requested a UDI 2-iron (18 degrees). Cink currently uses TaylorMade's RBZ 3-iron but said UDI offered a stronger flight that could help on the firm fairways at Royal Liverpool.

Ryan Moore had a UDI 3-iron (20 degrees) built for the John Deere Classic, and a 2-iron for The Open Championship. John Huh asked for a UDI 3-iron that could potentially fill the gap between his 4-iron and 17-degree hybrid.

Aldila unveils black Rogue shaft: Aldila's Rogue shaft is now available in a different tensile modulus (stiffness), torque and color. The company posted a photo on Twitter of a black Rogue shaft that had 110 msi and 2.8 degrees of torque; the original Rogue, which was used by John Deere Classic winner Brian Harman (Rogue 60X) in his TaylorMade JetSpeed driver, has 125 msi and 2.5 degrees of torque.

While the shaft has a slightly lower msi, it's still well above the average for carbon fibers that are historically used in TOUR-level shafts, which ranges from 33 msi to 65 msi.

Jordan Spieth goes back to old driver: Jordan Spieth switched to Titleist's new 915D2 (9.5 degrees) driver at the Quicken Loans National but went back to his 910D2 at TPC Deere Run.

Spieth finished T-7 and averaged 294.6 yards for the week with the same 910D2 driver he used to win last year's John Deere Classic.

"I've been using the driver since I was in college and have built up a comfort level with it," Spieth told PGATOUR.COM. "Also, the way it looks at address really fits my eye. A lot of the courses on TOUR put an emphasis on getting the ball in play and total driving, so being able to stand on the tee and know I can work the ball both ways and hit it solid is huge."

Harris English adds new wedge: Harris English became the latest Callaway staffer to add the company's Mack Daddy 2 Tour Grind wedge to the bag. English put in a 56-degree Tour Grind with 11 degrees of bounce.

Launched earlier this year at the Shell Houston Open, the Tour Grind is forged from 1020 carbon steel and has similar head shape to the popular X-Forged wedge that featured a higher toe and tighter heel-toe radius for increased versatility.

The relief on the heel and toe of the Tour grind helps the leading edge under the ball to hit open face shots without having the bounce come into play. A straighter leading edge also gives the wedge improved turf interaction.

PING G30 additions: PING saw additional players add the company's new G30 driver and metalwoods the week after the official TOUR launch at The Greenbrier Classic. Alex Prugh switched to a G30 driver, 3- and 5-wood while Daniel Summerhays put in G30 3-, 5- and 7-woods.

David Duval finds new putter: David Duval made a putter change the week prior to The Open Championship after testing out three Nike putters on the practice green. According to Nike Tour reps, Duval tested out a Method Mod 30, Method Mod 90 and Method 001.

Duval opted to go with the Method 001, a heel-toe design that features Nike's low-durometer Polymetal Groove technology on the face that was designed to reduce skidding on the greens and get the ball rolling faster.

Divots: Russell Henley had the loft and lie on his clubs checked to make sure all his specs were correct ... Greg Chalmers, who ranks fifth on TOUR in strokes gained - putting, switched to TaylorMade's Spider Mallet 72 putter. ... Nike Tour reps built Kyle Stanley a Nike VR Pro Combo 2-iron. ... Frank Lickliter II played TaylorMade's Project (a) ball.
