Earlier this week, GolfWRX Editor-in-Chief Ben Alberstadt reported the news of Dustin Johnson and Matthew Wolff being equipped at this week’s Sentry Tournament of Champions with the all-new TaylorMade SIM drivers which hit the USGA conforming list on Monday.

Ahead of round one at this week’s event, the company divulged further details on the new SIM additions in Johnson and Wolff’s bag as well as fellow TaylorMade golfer’s Jon Rahm and Collin Morikawa—including background behind the choices each man had made.

Dustin Johnson

As previously reported, during round one in Hawaii, Johnson played a 10.5-degree TaylorMade SIM Max driver with a 45″ Fujikura Ventus 6X shaft. According to TaylorMade representatives, Johnson has been extremely impressed with the consistency in spin rates, ball flight, as well as the extra head speed of the driver during testing.

The 35-year-old is also using a 15-degree SIM Max 3-wood with a 42″, 95-gram Project X HZRDUS Black shaft this week. Per the brand, Johnson made the decision due to the extra spin allowing him to carry 280-yards with the club, with the SIM Titanium 3-wood having too much ball speed, causing Johnson to carry the club too far.

Rounding out the SIM additions in Johnson’s bag this week is a 22-degree SIM Max Rescue club with a HZRDUS 105 Hybrid shaft.  According to TM, Johnson has been mightily impressed with its consistent 255-260 yard carry as well it being an anti-left rescue club for the 2016-U.S. Open Champion. As a side note, Thursday’s opening round was Johnson’s first-ever competitive round in his life playing a rescue club.

Johnson is also using the brand’s 60 and 54-degree new MG2 chrome wedges and per sources, the American loves the raw faces on the wedges. Johnson is also playing a Spider X Copper putter in Kapalua this week.

Matthew Wolff

Matthew Wolff got his year underway on Thursday at the Sentry TOC, and he did so using a 9-degree TaylorMade SIM driver with a Graphite Design Tour AD TP 7 TX shaft, as well as a 15-degree SIM Titanium 3-wood with a new Graphite Design Tour AD XC 8 TX shaft.

According to TM representatives, Wolff feels that the driver is more consistent and forgiving than what he had previously been using, and stated that he loves the “flight and spin this week with the hard winds.”

With the 3-wood, Wolff claims that the clubs offer him more versatility with shots, calling it the “the best 3-wood I’ve ever hit” as well as it giving the 20-year-old “incredible confidence looking down at the shape” of the club.

Jon Rahm

The Spaniard began his 2020 with a 10.5-degree TaylorMade SIM driver with the same 75-gram, 45″ Aldila shaft he’s played in recent years. Per company sources, increased ball speed and distance with the club saw him choose it over the M5.

Rahm is also using 15-degree SIM Titanium 3-wood at 16.5 degrees, as well as a SIM Titanium 5-wood, both set to launch higher. According to TM, Rahm made the adjustments due to faster and longer results, and that the 25-year-old loves the shape and look of his new SIM Titanium woods.

Rahm is also playing a 50-degree new MG2 SB wedge with fresh grooves to start the year.

Collin Morikawa

The Californian has begun his year with a TaylorMade SIM driver with the head adjusted two notches higher, with a Mitsubishi Tensei White 70 TX shaft. Per TM, Morikawa has seen a 1-2 mph increase in ball speed with this set-up and has found his new driver easier to control, with the spin in an excellent window for his preferred fade shot.

Morikawa is also using a 15-degree TaylorMade SIM Titanium 3-wood with an MRC D+ 80 TX shaft, which according to the company, has given the 22-year-old a higher launch and 10 yards more carry on average than he previously had.

Morikawa is also using a TP Soto putter as well as a TP5 golf ball this week in Hawaii.
