Just like the drivers, the Great Big Bertha
Epic and Epic Sub Zero fairway woods are both made with the
same ultra-light triaxial carbon.
The MOI in the Epic model has been increased by 11% on the XR16 thanks to the crown being 80% lighter than a steel equivalent, yielding much better performance from mishits.
Meanwhile, the Callaway Great Big Bertha Epic Sub Zero - like the Sub Zero driver - features adjustable weighting, with the ability to switch the positions of the 22g and 3g weights to create a choice between lower launch, spin and trajectory or higher launch, spin, and trajectory.
