When PING released the G15 iron in 2009, it was touted as a game-improvement model for amateurs that were looking for additional forgiveness and offset in a slightly larger profile.
Apparently K.J. Choi never got the memo, because he showed up to Augusta National with a set in his bag. While a majority of pros use irons that have a small profile, very little offset and a thin sole, Choi has consistently gone against the grain and used irons that have a thicker sole and offer additional forgiveness and yards in a beefier package.
Choi used the same set of G15 irons during the 2011 season -- the same year he won THE PLAYERS -- and went back to due to the comfort level and success he had with the sticks in the past.
Stricker goes back to old shafts: Steve Stricker switched to Titleist's 714 AP2 irons last week at the Shell Houston Open. He also added a new set of True Temper Project X 6.5 shafts, noting that he liked the kick the shafts provided.
One week later at the Masters, Stricker made an adjustment to the irons and returned to his KBS C-Taper (S+ flex) shafts.
"[I] didn't really feel all that comfortable with them," Stricker said, "so kind of went with some — I had to go back and redo the shafts and get my old set of shafts back in there."
Stricker finished T-31, hitting 51.39 percent of his greens in regulation.
Scott adds Vokey SM5 wedges: Adam Scott continued his recent trend of putting new equipment in play the week of the Masters.
During last year's dramatic win, Scott added Titleist's 913D3 driver. This year it was two Titleist Vokey SM5 wedges — a 48-degree F Grind with 8 degrees of bounce, and a 54-degree with 10 degrees of bounce. Instead of upgrading the lob wedge as well, Scott opted to stick with his trusty 60-degree Vokey TVD K Grind.
Louis Oosthuizen tinkers with putter loft: Tinkering with wedge bounce for Augusta National's firm turf is a fairly common equipment tweak. One that's less common is adjusting putter loft — something Louis Oosthuizen did to his PING Ketsch flatstick.
It's no secret that the greens at Augusta are lightning fast, so players want the ball to roll true off the putter face. The South African noticed the ball was bouncing a bit on long putts, so he reduced the loft on his putter to 2 degrees due to the speed of the greens.
By decreasing the loft on his putter, Oosthuizen was able to get the ball rolling sooner and reduce the chances of it skidding along the way.
Milled putter for Justin Rose: Justin Rose used a custom TaylorMade White Smoke DA-62 putter that was delivered to the 2013 U.S. Open winner the week of the Arnold Palmer Invitational.
Rose had been using an all-black Spider Blade with a True Roll insert but said the milled face gave him more feedback on mishits.
Divots: Graeme McDowell was spotted using a Callaway FT Optiforce driver. The former U.S. Open winner was a Callaway Golf staffer until 2010, when departed to join Cleveland/Srixon Golf. ... Par-3 Contest winner Ryan Moore switched to a 35-inch Odyssey Metal-X Milled putter (loft 2.5 degrees; lie angle: 70 degrees) after testing it in the run-up to the tournament.
