Sri Lankan off-spinner Muttiah Muralitharan is priming a new weapon to unveil during a limited-overs international series against Australia and England in December.
"I bowl it with my same action, a slightly flatter trajectory and it skids through faster than normal," Muralitharan was quoted as saying in Cricket Week magazine.
"I've been trying it, but only in the nets so far. I want to be able to perfect it."
Muralitharan plans to use the new delivery, similar to a leg-spin bowler's flipper, before the 2003 World Cup in South Africa, starting in February.

Australian Test captain Steve Waugh has said he would be happy to work under Ricky Ponting should he make Australia's one-day World Cup squad.
"I'm very happy just to be a player. I quite enjoyed it at Kent, letting someone else have the responsibility and all the headaches.
"I'd be very happy to be just a player in the side. I wouldn't have to be captain. Certainly not."
37-year-old Waugh has been working tirelessly on fitness and improving his form and has recently taken in a stint with English side Kent.
"I'm realistic. I know I'm going to need luck to make the World Cup squad," Waugh added.
Nasser Hussain and four Ashes team-mates will interrupt a much-needed break from international cricket to play in two star-studded indoor matches.
The England captain will lead a Great Britain side against a Rest of the World XI in a two-match series at Cardiff's Millenium Stadium.
Also featured in the Brit team are Rob Key, John Crawley, James Foster and Simon Jones.
England leave for Australia on October 17.
