Lofts compared
- Big Bertha Fusion
- Fusion Wide Sole
What the differences mean
Every club the two sets share has exactly the same loft, starting with a 33° 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.
The Big Bertha Fusion is a game improvement iron and the Fusion Wide Sole a super game improvement iron, so they sit one step apart on the forgiveness scale. The Fusion Wide Sole is the more forgiving design, with a wider sole, more offset and more perimeter weighting for high handicaps, beginners and slower swing speeds. The Big Bertha Fusion trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 10 to 25 handicaps.
The Big Bertha Fusion is listed as multi-material (titanium face cup, tungsten-loaded polymer core) and the Fusion Wide Sole as multi-material (titanium face cup, tungsten weighting, wide sole). Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
The Fusion Wide Sole arrived 2 years after the Big Bertha Fusion, 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 Fusion and Fusion Wide Sole share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
