GOLF: Tiger Woods will risk using a new set of irons as he bids to win his sixth World Golf Championship title this weekend.

The world number one has decided to switch to a new set of forged-blade irons .

"Obviously, there's always an element of risk any time you change clubs, whether it's any club in the bag," Woods said yesterday.

"But I think, if you try them out and test them out enough, then hopefully they'll perform."

Woods said his new irons were better balanced than the old set. "I think, overall, consistency in the heads has been the most significant factor I have found after practising with them," he said.

"The balance is consistent throughout the set. I found that was the biggest difference between my previous set and this set."

Woods is also looking forward to the challenge of the 7,246-yard Mount Juliet layout, which was designed Jack Nicklaus.

"II think the guys are going to shoot some really low numbers here.

"I don't think it's as difficult as a lot of courses he (Nicklaus) designs. The bunkers aren't quite as severe and deep as we're accustomed to seeing on most Nicklaus courses.
