Callaway Golf Big Bertha Irons
Callaway’s new Big Bertha irons feature a two-piece head that comprises a 360-degree steel cup face wrapped around a steel body. This design mirrors the face currently used in the company’s X2 Hot fairway woods and hybrids, resulting in an iron that offers wood-like performance characteristics – and corresponding distance gains.
The wrap-around face flexes like a metal wood to offer increased ball speeds, even on off-centre hits, which, Callaway claims, makes them up to two clubs longer when compared with the company’s now extinct Razr X HL irons. The yardage gain is, in part, boosted through the use of stronger lofts (the 6-iron is two degrees stronger than the Razr X) and longer shafts (by 3/8ths of an inch).
Like all previous Big Bertha irons, this new generation falls into the upper end of the game improvement category, although the sole width has a progressive design, with the long irons featuring a relatively wide, almost utility iron-like sole, while the short irons offer a much thinner, more workable sole. A low and forward weighting in the head shifts the centre of gravity lower to maximise MOI for added forgiveness and a higher launch angle.
Available in 3-PW (along with A and S wedges), the standard steel shaft is True Temper’s Speed Step 80, while the graphite option is a UST Mamiya Recoil.
