Lofts compared
- RocketBladez
- RSi 1
What the differences mean
At the 7-iron, the RocketBladez is 30.5° and the RSi 1 is 30.5°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 11 clubs both sets share, the RSi 1 averages 0.3° stronger, with the largest gap at the 3-iron (18° vs 17°). The pitching wedges are 45° and 44°; the stronger one leaves a 6° jump to a 50° gap wedge, which matters when planning wedge gapping.
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 RocketBladez is listed as investment cast with Speed Pocket sole slot and the RSi 1 as investment cast. With the build method this similar, differences in feel come down to head size, sole width, topline and offset rather than how the heads are made.
The RSi 1 came out 2 years after the RocketBladez, 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 RSi 1 is the stronger-lofted set — up to 1° stronger than the RocketBladez on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
