Callaway Golf Ladies RH Big Bertha Irons

By J.D. Chi

In 2008 the world's biggest golf equipment maker, Callaway Golf, introduced its latest innovation in women's clubs, the Big Bertha irons. The clubs look and feel different than the usual women's offerings, but the most unique feature is Callaway's "I-Brid" technology, which combines the versatility of hybrids with the consistency of irons. The long irons in this set are all I-Brids while the short irons are more standard irons, though with larger faces and lower centers of gravity that target the most common struggle that women have--getting the ball off the ground. These clubs also made the Golf Digest 2009 Hot List. Though Callaway has since updated their Big Bertha line of irons, the original women's Big Bertha Irons are still available on the secondary market. 


The ladies Callaway Big Berthas are fit with graphite shafts, have a mid kickpoint, a low/mid torque and weigh between 51 and 56 grams, depending on the club. The loft ranges from 22.5 degrees on the 4 I-Brid up to 44 degrees on the pitching wedge. Loft increases between 3 to 4 degrees between clubs. The lie on these clubs begins at 60 degrees on the 4-iron and increases by half a degree up to 65 on the pitching wedge.


The I-Brid technology is cutting edge and key factors are the the big sole of a hybrid, which allows the club to cut through the grass more smoothly combined with a lower center of gravity to get the ball in the air more quickly. The clubs also have large faces. These clubs replace the standard long and mid irons; the 4 through 7 irons in this set are I-Brids.

Short Irons

The 8 iron through pitching wedge have a more standard iron configuration, though as with all Callaway clubs, the club face is a bit oversized, allowing for a better opportunity to get a clean hit. The sole of the club is also a little wider than the norm and cuts through the grass more easily. These clubs are offset to limit slicing.


Callaway applied its "extreme notch weighting" technology to these clubs, moving the weight from the center of the club to the perimeter. Callaway is not the only company to use perimeter weighting, but it has pushed the weights to the absolute edges of the club head. This design produces more stability and greater distance, even when you don't hit the ball clean. In more technical jargon, a higher "moment of inertia" is created, which translates into a more forgiving club.

Special Technology

Callaway has taken much of its arsenal of technology and thrown it at this latest version of the ladies Big Bertha. The company applied its "variable face thickness" "S2H2" weighting system and its 360-degree undercut channel to the club head. The result is that the center of gravity for the club is lower and further back. In addition, Callaway modified its proprietary "Tru Bore" design to limit vibration during the swing.


The standard ladies Big Bertha set is made with a 38.5-inch 4-iron and a 35.5-inch pitching wedge. The I-Brids decrease in length by 3/4 inch. There is a half-inch difference between the 7 I-Brid and 8-iron and a quatter-inch between the 8-9 irons and 9-iron to pitching wedge. The clubs may be custom fitted if you are exceptionally tall or short.
