What the differences mean
At the 7-iron, the Gravity Back is 33° and the King Cobra SS Oversize is 34°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Gravity Back should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the King Cobra SS Oversize. Across the 12 clubs both sets share, the King Cobra SS Oversize averages 0.2° weaker, with the largest gap at the 7-iron (33° vs 34°). The pitching wedges are 46° and 45°; the stronger one leaves a 5° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the Gravity Back 7-iron sits 0.5° flatter (62° vs 62.5°), which nudges start direction slightly right for a right-hander; the Gravity Back 7-iron is 0.25 inches longer (37.25" vs 37").
The sets are built differently: the Gravity Back runs 1-iron to LW (13 clubs), the King Cobra SS Oversize 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 Gravity Back is listed as investment cast, backweighted low-profile perimeter-weighted cavity and the King Cobra SS Oversize as oversize investment cast cavity back with tungsten inserts in the long irons. The King Cobra SS Oversize adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The King Cobra SS Oversize came out 3 years after the Gravity Back, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The King Cobra SS Oversize is the weaker-lofted set — up to 1° weaker than the Gravity Back. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
