Brandt Snedeker's older model TaylorMade Burner SuperFast driver remained in play at the RBC Heritage, but one of the oldest clubs in the five-time PGA TOUR winner's bag could be on its way out.

Snedeker started working extensively with a new TaylorMade RBZ Stage 2 driver (9 degrees with a 46-inch Aldila Tour Blue 65TX shaft) at an event on Tuesday and during Wednesday's pro-am.

Palmer goes to TaylorMade Daddy Long Legs: Ryan Palmer has tried various putters over the years, but his Odyssey Dual Force Rossie II has always found its way back into the bag. The putter has been with Palmer for almost his entire professional career and helped him win two of his three PGA TOUR titles.

Palmer may go back to the putter at some point, but for at least one week he decided to shelve his trusty sidekick for a 35-inch TaylorMade Daddy Long Legs putter. Intrigued by the counterbalanced putter -- Daddy Long Legs was released at retail this week -- Palmer decided to give it a test drive early in the week before putting it in play on Thursday.

While the putter is 35 inches, Palmer said he plans to choke down a couple inches on the grip. He also noted the high MOI and stability of Daddy Long Legs' shape and counterbalance grip (which is 130 grams) helped him keep the ball on his intended line -- especially on putts from inside 20 feet.

Callaway X-Hot 3Deep a perfect fit at Harbour Town: One of the tighter courses on the PGA TOUR schedule, Harbour Town requires pinpoint accuracy and distance control off the tee. Long hitters rarely have to pull driver out of the bag, preferring instead to use a 3-wood to keep it in play.

It shouldn't come as a surprise that Callaway saw a bump in X-Hot 3Deep requests early in the week. Looking for a club with the workability of a 3-wood in a mini-driver package, a number of players, including Ryo Ishikawa and Luke List, decided to give Callaway's newest creation a try.

Ishikawa went with a 14.5-degree (actual loft 13.9 degrees) that was built for him at the Shell Houston Open. The course-dependent club has a 43-inch Graphie Design Tour AD GT-8 TX shaft with a custom Graphite Design cord grip.

Luke List had Callaway reps build him a 14.5-degree with a 43.5-inch Oban Kiyoshi Black 90x shaft. List initially went with his Mitsubishi gamer shaft but felt his spin numbers were too high. The Oban rectified the problem and allowed him to maintain the same trajectory and distance off the tee.

Daly adds Adams DHy driving hybrids: Adams' DHy driving hybrid has replaced a number of long irons on the PGA TOUR over the past several weeks. John Daly is one of the latest to added two to the bag. One is an 18-degree opened 16 degrees, specifically for tee shots at Harbour Town. The other is a 21-degree, bent to 22.5 degrees, that currently serves as a 3/4 iron replacement.

Kaymer goes with TaylorMade R1 driver: The week following the Masters is usually one where you'll see players start working with new equipment. Martin Kaymer was one of the noteworthy names after he dropped his TaylorMade RBZ Tour driver for an 8-degree TaylorMade R1 with a Graphie Design Tour AD shaft.

Kaymer noticed R1 was beating RBZ Tour in comparison testing during the week and finally pulled the trigger.

Pettersson makes 3-wood change: Carl Pettersson spent an extended amount of time on Monday testing 3-woods on the the driving range. Pettersson went with a 13-degree Nike VR_S Covert Tour with a neutral face-angle setting because he liked the club's ball flight and felt it gave him the best chance to work the ball around Harbour Town's tight layout.

Divots: Rory Sabbatini prefers to grind his own wedge, but when he switched from a 60-degree TaylorMade TP xFT (Exchangeable Face Technology) to a new 60-degree TaylorMade ATV prototype at Hilton Head, he didn't touch the sole. Sabbatini noted the performance and versatility of ATV allowed him to keep the wedge as-is ... Stuart Appleby became the latest player to change to Callaway's HEX Chrome+ ball. Appleby preferred the softer feel and quieter sound around the green ... In an attempt to close the distance gaps at the top end of his bag, Patrick Reed went from four wedges to three and added a 19-degree Nike VR_S Covert 5-wood. The 5-wood plays more like a 4-wood due to the ball flight, and Reed was able to tweak his wedge gap and go with a 54-and 59-degree Nike VR Pro setup ... A traditional muscleback iron player, James Driscoll switched to TaylorMade RocketBladez Tour following several weeks of meticulous work in comparison testing ... Robert Garrigus kept a 25-degree Adams Super LS hybrid in the bag at Hilton Head after using it at the Masters. Garrigus generally only uses a 22-degree Adams Super S but likes the versatility of the 25-degree.

HILTON HEAD, S.C. -- Carl Pettersson has one of the more interesting driver setups on the PGA TOUR with 11.5 degrees of loft in his Nike VR Pro STR8-FIT driver, among the highest lofts in professional golf.

Not only that, his driver is 46.5 inches long, which is roughly 2 inches longer than the average driver shaft on the PGA TOUR. To put things into perspective, Bubba Watson, who's 6-feet 3-inches tall, plays a 44.75-inch shaft in his PING G25 driver. Pettersson, on the other hand, is 5-feet 11-inches.

Pettersson went with the unique setup last year because he believe the additional loft and longer-than-average shaft allowed him to increase carry with more spin. It seemed to be the perfect formula when Pettersson won the RBC Heritage last year with the driver in the bag.

As he returns to defend his title this week at the RBC Heritage, Pettersson still has the same driver in the bag, but following a range session on Monday, he decided to switch up the shaft, pulling the Fubuki Alpha 50 shaft (50-gram) for a sub-40 gram Project X PXv 39 shaft.

Weighing in officially at 39.5 grams and 46 inches raw length, PXv 39 is the first PGA TOUR-caliber graphite shaft that weighs under 40 grams and can handle high swing speeds.

Pettersson tried the shaft last year at the Northern Trust Open and liked it enough to consider putting it in his driver if he wanted to switch things up. 

According to True Temper Tour Manager Simon Wilson, Pettersson was flying the back net at Harbour Town's practice range and opted to go with the shaft because it created more swing speed. 

Assuming the shaft stays in the driver, Pettersson would be the first player on the PGA TOUR to use the PXv 39 shaft in competition.
