Callaway 2009 line-up revealed

The Callaway Big Bertha Diablo range includes a driver, fairway wood, hybrid irons and ball. The all-titanium headed driver is available in two models, neutral and the unusual looking draw model. In the draw model the head has been shaped with more mass in the heel of the club to encourage a right-to-left flight. The unique shape of the club moves the majority of weight low and deep in the head. The placement of weight is also designed to help close the clubface at impact and release the club with more power. The fairway woods incorporate the sametechnology and are available in 16º, 18.5 º, 21º, and 23.5º lofts. Tour heads are available in 13º, 15º and 18º lofts.

The Big Bertha Diablo irons are a premium forged head designed for players who want a traditionally styled club with enhanced playability. The head has a thin top-line with a narrow sole and minimal offset. A rubber cavity dampens vibrations and fine tunes the sound of each iron.

The Big Bertha Diablo ball is a 2-piece design with Hex aerodynamics to reduce drag and increase distance.

The range will be available from March 2009.
