London: World number five Graeme McDowell, who enjoyed the best season of his career in 2010, will use new clubs this year.
The 31-year-old Briton, who won the US Open last season and also claimed the winning point for Europe in the Ryder Cup, has decided to switch manufacturer from Callaway to Srixon.
"I am really excited about my decision," he told his official website on Monday.
"There is a great energy among the team... regarding my signing with them and I looking forward to feeding off this energy going into 2011."
According to media reports, the U.S. Open champion has signed a multi-year deal with his new suppliers worth about $3 million a year.
McDowell, who won three times on the European Tour last year and beat Tiger Woods in a playoff at the Chevron World Challenge in California in December, is to use his new equipment for the first time in this week`s Tournament of Champions in Hawaii.
The Northern Irishman will be paired with American Hunter Mahan, the player he beat in the last-day singles at the Ryder Cup, in the US PGA Tour`s season opener at Kapalua.
"As a golf fan, one of the most compelling moments of 2010 was their final-day match-up during the Ryder Cup," said tournament director Nancy Cross.
"To have these two paired together for the start of the season... we couldn`t have scripted it better."
