Both Si Woo Kim and Nicolai Hojgaard are giving a clinic with their Callaway drivers in very different ways this week.
The pair enter the final round of the WM Phoenix Open tied for second place at 12 under par, one shot behind Hideki Matsuyama and sit third and fourth in Strokes Gained: Off the Tee this week.
Kim does this while leading the way in driving accuracy, hitting more than 80 percent of his fairways, while Hojgaard does it with a combination of distance (T22, 320 yards) and accuracy (T12, 67%). The different ways they play require vastly different driver setups, but the common denominator is that both players have recently moved to different versions of Callaway’s new Quantum Triple Diamond platform.
Keep reading below for a more detailed dive into their settings.

As we wrote in the Tour Report two weeks ago, Kim finally gave up his Paradym Ai-Smoke Triple Diamond driver that he had held on to for the past two seasons.
“It was almost plug and play,” said Callaway Tour Content Manager Thompson. “I mean, there really wasn’t a lot of work done with Si Woo. He took a few shots and said, ‘This thing is amazing,’ and it literally was.”
Kim isn’t one of the faster players on Tour, so he’ll take advantage of any meaningful speed gains he can make. It also lives on the higher side of the spider threshold, making killing spiders as much of a priority.
That’s why you see him playing the more compact Triple Diamond model as opposed to the Triple Diamond Max.
The starting line was also important for Kim to transition from his Ai Smoke. That’s why you’ll see below in his specs that he keeps the back weight on the heel side of the club to encourage a left starting line.
With the new driver, Callaway Tour representative Kellen Watson said Kim added about 2 mph in ball speed and reduced his spin delta to just 400 rpm. They wanted to make a substitution last fall during the PGA Tour’s RSM Classic, but the driver was not yet on the compliant list.
“He loved that we went back to the top line and crown of AI Smoke and loved the look at address and the sound,” Watson told GOLF. “Easily one of my favorite player and caddy combinations. The hardest part is getting him to play the new thing yet, but the numbers tell us it was a no-brainer.”

Nicolai Hojgaard
Hojgaard, meanwhile, is in the upper echelon of speed on the PGA Tour and already ranks second in ball speed this season after finishing third in driving distance a year ago.
His switch to the Quantum Triple Diamond Max driver took a little more time, but he made the switch this week and it is paying off.
For all his speed, Hojgaard plays with more stability and spin (high 2000s) than you might think. He uses a high-loft Triple Diamond Max, the more stable of the two Triple Diamond platforms, with a Fujikura Ventus TR Blak at just over 45″.
“While this could be more efficient from a distance perspective, this higher spin setup gives him ultimate control,” said Callaway Tour Rep Zach Smith. “He still has a ball speed of almost 190 with the triforce technology, so he doesn’t really give up anything against the pitch.
“Nico has one of the most efficient deliveries on tour and has a lower spin loft, meaning he is always on the low side of the spin, so we are always working to increase his ability to control the ball.”
He also plays the Chrome Tour X+ golf ball, a spinnier version of the Chrome Tour
