McIlroy back with TaylorMade SIM driver, switches to SIM Max 3-wood

Rory McIlroy has reverted back to his SIM driver and switched to a SIM Max 3-wood at this week's Travelers Championship, according to TaylorMade.

McIlroy, who got off to a flying start at TPC River Highlands with an opening 7-under 63 on Thursday, averaged a whopping 328 yards driving distance with his TaylorMade SIM driver.

The World No.1 decided on using a SIM Max driver at the RBC Heritage last week, but went back to the SIM this week. 

"Rory is back in the SIM driver this week," a TaylorMade rep confirmed to GolfMagic.

"He's in SIM 8.0, so one click higher. Although he loved the SIM Max driver, he wanted to see a straighter face than the slightly open SIM Max from last week. The numbers on Trackman were great."

McIlroy also decided to switch up his 3-wood at the last minute by opting for the SIM Max instead of the SIM, simply because he was hitting it too far. 

"Rory also switched his SIM 3-wood late Wednesday," confirmed our TaylorMade rep.

"The SIM 3-wood he’s been playing all year is travelling a little too far, carrying some 300 yards.

"He’s a little faster now than when he was fit into the 3 wood in January, so we needed to adjust to take account of his increased speed.

"Rory is now in a SIM Max at 15 degrees because it spins more and won’t go as far."

Other changes among the big-name TaylorMade players competing this week include Dustin Johnson adding a new TaylorMade Truss TB1 blade putter and tweaking his SIM Max Rescue. 

"DJ played around with loft, lie and swing weight until it felt and looked perfect to him," TaylorMade told GolfMagic. 

"He has also got a new SIM Max Rescue built at 19 degrees. The one he had was at 20 degrees and flying 257 yards, but he needed it to go 265 in the air, so we built another one at 19 degrees for him. He was easily hitting it 265 plus."

Jason Day has switched from a SIM to a SIM Max driver, and has made a number of loft adjustments to his setup. 

"Jason is playing a SIM Max driver in 10.5 degrees, so one click lower," said TaylorMade. 

"He loves the flight and most importantly the consistency on mishits. 

"Jason has also added loft to most of his irons and wedges, and is starting to swing really good. The irons were going too far for him, and the gaps were too large because of this. 

"He also wanted his 3-iron to go five yards further, so we built a P790 3-iron into the same specs as his P760. With the increased ball speed from the P790, he got that 245 yards carry number that he wanted."

Matt Wolff has mixed things up on the greens by going for a chalk Spider X putter.

"Matt has opted for a chalk Spider X putter with a slant neck," said TaylorMade. "He has been playing face balanced and was feeling like he was having trouble getting the putter to arch in the stroke. 

"He went to the slant neck and it made things so much easier for him to start his ball on line. It also has a sight line just like his old Spider."
