Thompson entrusts Craig Allan, director of Sea Island’s Golf Performance Center, who works with various PGA TOUR players on their fitting needs. Last year, Thompson informed Allan that something wasn’t right with his irons. He’d been striping his driver with a Titleist ’21 Pro V1 and Titleist TSR3 driver, but he was struggling with distance control with his irons due to low spin, while catching too many fliers out of the rough.

Allan offered Thompson three solutions: weaken the lofts of his current irons, test out some higher-spinning golf balls, and test out different iron heads and shafts. Thompson didn’t want to hit the ball higher with his irons; he wanted to address the golf ball instead. Initially, Thompson decided to change into a Titleist Pro V1 Star prototype golf ball that offers higher spin rates.

Although the ball change provided a nice solution for his iron play, his driver play suffered.

“(At the) Memorial (Tournament presented by Workday) last year, I started playing a spinnier Titleist golf ball, and it was great for my iron setup at the time,” Thompson said. “But kind of over time I saw my driver’s stats kind of go down, which is kind of a strong suit of my game. So we were trying to figure out after Valspar (Championship) this year how we can get the driver back going.”

Following the Valspar, Thompson and Allan got back to work in the testing center. Thompson was ready for Allan’s third option, which meant he would switch back into his previous Titleist Pro V1 ’21 golf ball, restore his driver dominance, and begin looking at different iron heads with weaker lofts and different shafts to gain spin and distance control.

After two weeks of testing different iron head-and-shaft combinations with the lower spinning golf ball, Allan and Thompson decided on the Titleist 620 MB irons (5-9) equipped with True Temper Dynamic Gold Mid Tour Issue X100 shafts, which offer slightly higher spin and launch compared to the True Temper Dynamic Gold Tour Issue X100 shafts that Thompson was playing previously.
