When it comes to changing golf clubs on the PGA Tour, most golfers like to take their time. They spend the entire off-season tweaking, testing and dialling in (I can't stand that phrase) their new clubs until they feel comfortable enough taking them inside the ropes.
For many world class golfers, it's a process. Not a 24-hour quick fix. That's why it somewhat comes as a shock to learn Spain's Rafa Cabrera Bello had a full bag fitting during last week's US Open and stuck all of his new clubs in play straight away at Winged Foot.
Then again, after five missed cuts since golf's return in June it probably wasn't the toughest decision he's ever had to make.
To the Spaniard's credit, he enjoyed a solid week at the second major of the year, moving right into contention heading into the weekend following rounds of 68 and 70.
Unfortunately he slipped back into the pack over Saturday and Sunday with rounds of 74 and 78, but he finished in a respectable tie for 23rd, despite finishing 16 strokes behind eventual US Open champion Bryson DeChambeau.
According to a Golf WRX report on what happened, the World No.67 played with his new Titleist clubs for the first time on Monday and had stuck them in his bag by the Tuesday.
Cabrera Bello was initially using the Titleist TS3 driver in 8.5 degrees and replaced it for a TSi3 driver in 9.5 degrees, with a change of shaft from a Project X HZRDUS Yellow 75 6.5 to a Project X HZRDUS RDX Blue 60 TX.
He also changed his 3-wood and 5-wood from a Titleist 915F to a new Titleist TS3 in 15 and 18 degrees, again with a change of shaft from a Project X 10A2 100 7.0 to a Project X HZRDUS RDX Black 80 TX.
There was also a radical switch in his irons. Out went the Titleist 718MB irons from 3 to PW and in came a Titleist U500 in 3 and 4-iron, and Titleist 620MB in 5 to 9-iron with Project X LZ 6.5 shafts as opposed to his former Project X LZ 7.0 130 shafts.
He also switched his wedges from Vokey SM7 Tour Chrome to Vokey SM8 in 48, 54 and 60 degrees with Project X LZ 6.5 shafts.
Cabrera Bello did, however, maintain his Scotty Cameron Tour Rat Newport 2 putter, and he remains with the Titleist Pro V1 X golf ball.
