Lofts compared
- Hawk Eye VFT
- Big Bertha Fusion
What the differences mean
At the 7-iron, the Hawk Eye VFT is 33° and the Big Bertha Fusion is 33°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 12 clubs both sets share, the differences roughly cancel out, with the largest gap at the 9-iron (42° vs 41°). The pitching wedges are 46.5° and 46°; the stronger one leaves a 4° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Hawk Eye VFT runs 1-iron to LW (13 clubs), the Big Bertha Fusion 2-iron to LW (12 clubs).
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 Hawk Eye VFT is listed as cast titanium with Variable Face Thickness and tungsten weighting and the Big Bertha Fusion as multi-material (titanium face cup, tungsten-loaded polymer core). Both use tungsten weighting to lower the centre of gravity and steady the head on off-centre strikes.
The Big Bertha Fusion arrived 2 years after the Hawk Eye VFT, 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 is the stronger-lofted set — up to 1° stronger than the Hawk Eye VFT on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
