Callaway Ladies Big Bertha 2008 irons. New for 2008, this latest version of legendary Big Bertha irons are aimed specifically at the Ladies market. Women now can play with clubs that take the guesswork out of their set configuration. These technologically advanced stainless steel clubs consist of i-brids instead of hard-to-hit long irons, and super game-improvement mid and short irons. Each club has a wide sole design that improves turf interaction and a low, deep CG that helps get the ball in the air quickly and easily. The shafts are slightly longer to better match the average woman's height and the lofts, lie angles and club weights are optimized.
