DORAL, Fla. -- Dustin Johnson had a difficult time settling on one putter over the last few weeks. After opening the season with a Titleist Scotty Cameron Newport 2 prototype putter, Johnson switched to an Odyssey Versa No. 7 at the Northern Trust Open and then promptly dropped the putter for a Scotty Cameron Notchback prototype two weeks later at The Honda Classic.

The putter drama continued for Johnson at the World Golf Championships-Cadillac Championship when he showed up with the Titleist Scotty Cameron Newport 2 prototype in the bag.

Players switch putters all the time, but in his last four starts, Johnson has used three different putters. With the Masters nearly a month out, it would appear as if the seven-time PGA TOUR winner is struggling to find a putter that gives him confidence on the greens.

Johnson also practiced at Bear's Club on Tuesday with a set of TaylorMade RocketBladez irons — the same irons he used when he won the Hyundai Tournament of Champions — and brought them to Trump Doral on Wednesday for a practice round.

Johnson went back to his TaylorMade Tour Preferred Forged MB irons at the Northern Trust Open and kept them in the bag this week.

Mahan switches shafts in Ping G25 3-wood: Hunter Mahan worked with Ping Tour rep Matt Rollins to get a new shaft in his 15-degree (actual loft 14 degrees) Ping G25 3-wood that allowed him to turn the ball over. Mahan, who was using a Graphite Design GT 8X shaft, settled on a Matrix XCON 8X3 shaft that was tipped 1 inch following a testing session on Wednesday.

Woods tests Nike Method 001 backup putter: Tiger Woods tested a number of Nike clubs during Wednesday's practice round, including two Nike Method 001 putters. Woods currently uses the same model but wanted to make sure he was comfortable with his backups as well.

Els adjusts Callaway RAZR Fit Xtreme driver: Looking for a more draw friendly driver, Ernie Els added RAT glue to the heel and reduced the toe weight (from 14H/3T to 2 grams of glue in the heel plus the 14 gram weight and a 1 gram weight in the toe) in his 9.5-degree Callaway RAZR Fit Xtreme driver. Following the adjustment, Els was drawing the ball with ease.

Van Pelt switches to TaylorMade RocketBladez: Bo Van Pelt spent the early part of the season testing TaylorMade's RocketBladez Tour irons, but it wasn't until last week — Van Pelt wasn't in the field at the Honda Classic — that he had time to really work with the irons for an extended period.

Encouraged by the numbers he saw during testing — higher ball speed, steeper descent angle, and the consistency on mis-hits — and the way the irons performed in 25 mph winds at Seminole Golf Club, Van Pelt brought the irons to Trump Doral and put them in play on Thursday.

Nike athletes gear up for Masters with new grooves: In preparation for the greens at Augusta National, a number of Nike staffers, including Thorbjorn Olesen, Nick Watney and Carl Pettersson, received new wedges with fresh grooves at the WGC-Cadillac Championship. While most didn't put the wedges in the bag right away, Nike said the goal is for the players to work them in over the next few weeks.

Divots: Due to the course conditions at Trump Doral, Rory McIlroy decided to take out his Nike VR Pro Limited Edition 5-wood and put in the bag his VR Pro Combo 2-iron. ... Cleveland Tour reps built Graeme McDowell a couple Classic drivers (same specs as his current gamer) with a bit more loft to draw the ball. ... David Lynn, who arrived at Trump Doral off a top-5 finish at the Honda Classic, swapped out his 2012 RBZ fairway wood for a new 14.5-degree TaylorMade RBZ Stage 2 Tour after seeing as much as 7-10 yards more compared to his gamer. ... Thorbjorn Olesen started testing Nike VR_S Covert Tour hybrids early in the week but didn't put one in the bag.

Nicolas Colsaerts is the second PGA TOUR player to play the Odyssey Tank putter.

By Jonathan Wall, PGATOUR.COM Equipment Insider

DORAL, Fla. — Nicolas Colsaerts became the second PGA TOUR player to put Odyssey's new Tank putter in play this season — Matt Every was the first at the Northern Trust Open — when he used a 40-inch version on Thursday at the WGC-Cadillac Championship.

The Belgian, who joined Callaway Golf at the beginning of the year, had been using a conventional Odyssey Black Series i #1 for the last few months, but when he showed up at TPC Blue Monster at Trump Doral on Monday, he decided to give the counterbalanced model a test run.

Colsaerts spent the first three days working with a 40-inch version of the putter, which uses a counterbalance weight, heavier 400-gram head and heavier 150-gram shaft to quiet the hands during the stroke.

The additional weight in the putter is supposed to engage the big muscles to promote a more pendulum stroke that helps keep the wrists from breaking down. Odyssey officially launched Tank — which is the company's alternative to anchoring — this week at the WGC-Cadillac Championship.

The putter comes in short (34- and 36-inch) and long (38- and 40-inch) models. The short model has a total club MOI that's 34 percent higher than a standard putter, while the long option is 109 percent higher than a standard putter.

Tank's balance point is also lower on the shaft, providing a more conventional approach that players like Colsaerts prefer.

While Colsaerts didn't make any major adjustments to his Tank, he did have the White Hot insert tweaked for added consistency.

The putter comes to retail on April 15th.

Tiger Woods opened the World Golf Championships-Cadillac Championship with a new Nike 5-wood in the bag, shelving his old 19-degree SasQuatch 2, which had been in play since 2007, for Nike's new VR_S Covert (19 degrees) model.

The switch produced a positive result for Woods, who opened the week with a 6-under 66 on Thursday that included nine birdies and currently has him tied for the lead.

“The 5-wood that I used is the SQ, so it's, what, three versions ago,” Woods said. “I finally put one in play that I felt comfortable with. I hit it a little bit further, so there's a little bit bigger gap between the 3-iron and the 5-wood but I can hit this 5-wood a little bit higher, so I can actually take something off it and throw it up in the air, which is nice.

“So even though that gap is a little bigger, I still have the option of being able to spin it up in the air.”

The VR_S Covert 5-wood still has the Mitsubishi Diamana BB 103x shaft Woods was using in his SasQuatch 2.

Woods played TPC Blue Monster at Trump Doral's back nine on Wednesday afternoon and spent time working with the VR_S Covert, as well two different Nike Method putters. Woods also had a second VR Tour driver on the range that looked almost identical to the version he currently has in the bag.
