Lofts compared

- Big Bertha OS
What the differences mean
Every club the two sets share has exactly the same loft, starting with a 30° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show.
Both are game improvement irons, built for roughly 10 to 25 handicaps. Perimeter-weighted cavity backs with wider soles, more offset and stronger lofts, aimed at mid handicaps. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
The Big Bertha (2014) is listed as hollow body, multi-material and the Big Bertha OS as investment cast. The Big Bertha (2014)'s hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the Big Bertha OS, at some cost in feel. The Big Bertha OS adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The Big Bertha OS arrived 2 years after the Big Bertha (2014), a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The Big Bertha (2014) and Big Bertha OS share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
