Tiger Woods, who rarely makes equipment changes, has been tinkering a bit with his driver. A few weeks ago, he experimented with different shafts before returning to his tried and true Mitsubishi Diamana Whiteboard 83-gram shaft. At the Memorial, he changed lofts, going from a 9.5-degree head in his Nike SQ Dymo to 10.5 degrees.

"I went with a little more loft, 10 degrees," Woods said. (A Nike Golf press release noted that the head was actually 10.5 degrees with the effective loft of 10 degrees.)

"As my release has changed over time with Hank [Haney], I needed a little more loft to get the ball in the air, little more stem. Still hitting it just as far but probably a different way."

For the week, Woods averaged 298.4 yards off the tee (T-12) and was second in the field in driving accuracy with 87.5 percent, including 14 of 14 on Sunday.

Woods' driving accuracy may have also been improved because he used a fairway wood off the tee, especially during the weekend.

"I used it a lot more once the fairways got faster," Woods said of his Nike SQ2 3-wood. "As the fairways got faster and faster, a low 3 wood and even a low 5 wood at times would go almost 300 yards. The 5-wood down 17 went 290 or something. Don't normally hit it that far."

Woods also put a set of Nike's Forged Blades in his bag, swapping them for the Victory Red TW blades he used to win at the Arnold Palmer Invitational in March.

As far as upcoming changes to the bag, Woods said he is happy with his current clubs.

"As of right now, I think I'm going to stick with the same set of clubs, all 14," he said.
