It's for: Traditional players seeking forgiveness
Luke Williams, Director of Innovation, Callaway Golf: "Big Bertha irons offer the ultimate in forgiveness with increased offset, a large effective hitting area and a constant width sole that helps turf interaction. This Big Bertha offers traditionally shaped long irons for those who prefer an iron look over our i-brids."
How it works: Last year, Big Bertha featured i-brid long irons (3-5) exclusively. Now you have the choice of i-brids or more conventional long irons. Either way, you get plenty of perimeter weighting plus variable face thickness to ratchet up ball speed.
From Golf Magazine:
The Big Bertha brand has been synonymous with ultra-forgiving irons since it was first stamped on a set more than a decade ago. For 2008, this stainless steel classic gets modernized. The most striking change is to the long (3-, 4- and 5-) irons. Dubbed "i-brids," these hybrid-like long-iron replacements are built for control (like irons), as well as distance and versatility (like hybrids).
In fact, each iron in the set has more mass lower and toward the heel and toe than the previous Bertha (released in 2006). The new center of gravity is 30 percent farther back from the clubface; the combined inertia (the club's ability to resist twisting) from heel-to-toe and topline-to-sole is 33 percent greater. In short, this Bertha is one straight shooter.
