Lofts compared
- Great Big Bertha Tungsten Titanium
- Hawk Eye
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.
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 Great Big Bertha Tungsten Titanium is listed as cast titanium with tungsten insert and the Hawk Eye as cast titanium with Tungsten Weight Matrix. Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
The Hawk Eye arrived 3 years after the Great Big Bertha Tungsten Titanium, 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 Great Big Bertha Tungsten Titanium and Hawk Eye share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
