Before Saturday's third round of the Quail Hallow Championship, Tiger Woods reverted back to playing with a Mitsubishi Diamana White Board driver shaft in his driver. On Wednesday during his practice round, Woods used an Aldila Voodoo XPP8 shaft in his Nike Dymo 380 driver. On Thursday, The Shop Blog broke the news that Woods was using a prototype Oban Mach 4 shaft.While Tiger had averaged 316 yards per drive, he sprayed tee shots both left and right. In fact, the world's No. 1 player hit just 30% of the fairways on Thursday and Friday. On Saturday, Woods hit 64% of the fairways while averaging 304 yards per drive.It's important to remember that driving accuracy stats don't take into account what club a player choses to hit off the tee on par 4s and par 5s. On the same course, under different playing conditions, Woods and other golfers may hit different clubs off the tee, making round-to-round comparisons challenging.UPDATE: Tiger Woods has the Mitsubishi Diamana White Board driver shaft in his driver again on Sunday.Stay in the know by following David Dusek on Twitter.
