Is Adam Scott using a Graphite Design Tour AD DI shaft? Is it custom black or is that a new one from them? -- Zach Gothard
Adam Scott has actually been using a Graphite Design Tour AD DI-8 X shaft in his driver for the last few years. If you're unfamiliar with Graphite Design's Tour AD DI -- the "AD" stands for accuracy and distance, and the "DI" for deep impact -- it's the company's best-known shaft and debuted on TOUR in the fall of 2009.
Ranging in weight from 53.5 grams to 84.5 grams, depending on the shaft flex, the Tour AD DI has a mid bend profile and stiff tip section that produces a higher trajectory with low spin.
Tiger Woods had been using the Graphite Design's Tour AD DI-7 X since the 2010 Masters before going back to a Mitsubishi Diamana White Board 73X shaft this year at THE PLAYERS Championship.
While the retail version Woods used had an orange paint job, Scott was looking for a more subdued version and had Graphite Design build him a custom black AD DI 8.
The shaft was a one-off version until this year, when Graphite Design announced the Tour AD DI line would be available, starting Aug. 15, in three weights -- 60-gram versions in SR, S and X flexes, and 70- and 80-gram versions in S and X flexes -- in Scott's custom black shaft color.
Please tell us more about these Titleist Vokey Design TVD-K wedges. Do I have to order them or will they be widely available? -- Steve Hawley
If you had the chance to watch last week's PGA Championship, you may have noticed first-time major winner Jason Dufner using a 60-degree Titleist Vokey Design TVD-K wedge at Oak Hill.
Dufner, along with 2013 Masters winner, were instrumental in helping master wedge craftsman Bob Vokey design the new K-grind -- a wedge that features a wider, more cambered sole that's perfect for soft sand/turf conditions and golfers that dig at the ball.
“The TVD-K is the evolution of the TK grind that we had on TOUR and as a limited release in WedgeWorks,” Vokey said. “It has a wider sole, with more camber. It has enough bounce to be very forgiving out of the bunkers but still allows shotmaking around the greens."
The K-grind comes in three lofts -- 56.12 degrees, 58.10 degrees and 60.10 degrees -- and, according to Vokey, is currently the second-most popular grind on the PGA TOUR behind the M-grind (TVD-M).
Dufner, the first Titleist staffer to use the TVD-K in competition, has been using a hand ground mid bounce version with 8 degrees of bounce and extra heel relief. Scott's lob wedge has 10 degrees of bounce, which is the exact same version you can buy on the Vokey website.
The TVD-K debuted in March and can be purchased directly through Vokey's WedgeWorks program for $160.
