- Sword Prime

First Impressions
The Storm Sword Prime was released in September 2016 as an overseas release, making it available exclusively on the international market outside the USA. Visually, the ball comes in a combination of Black Solid and Pink Pearl – an eye-catching but restrained color scheme that clearly sets itself apart from the flashier designs of many domestic releases. At the heart of the Sword Prime works the proven C³ Centripetal Control Core, a symmetrical two-piece core that became known in Storm's product history primarily through the successful !Q Tour series. This core is characterized by a quick rev-up and a controlled, smooth change of direction on the backend. At 15 pounds, the numbers come in at a 2.490 RG and a 0.029 differential, which points to a rather moderate flare potential and an early but controlled roll. The 16-pound version shows somewhat more dynamic numbers with a 2.48 RG and a 0.050 differential. The cover is the Reactor Hybrid Reactive coverstock with a factory finish of 2000 grit, polished. The Reactor material is considered the base chemistry for later developments such as R2S™, R3X™ and R4S™ and has been a fixture in the Storm portfolio for over a decade. In the hybrid version it should offer moderate aggressiveness combined with good control, without overreacting on the backend. The combination of polished finish and hybrid cover should provide clean length through the heads before the ball reacts to friction in the midlane.
Comparison
The Sword Prime fits into Storm's Sword product line, which was designed primarily for the international market and presents the C³ Centripetal Control Core in various coverstock variants. Compared to the Storm Sword (Reactor Solid, polished), the Sword Prime should offer a somewhat more versatile backend reaction thanks to the hybrid version of the Reactor coverstock – the solid portion reads the midlane, while the pearl portion should provide a bit more length and a more defined hook. The Storm Sword Nano uses the same C³ core but pairs it with the more aggressive NRG Smooth Hybrid coverstock at a 4000 Abralon finish, which should predestine it for oilier conditions. The Storm Sword Perfect, on the other hand, relies on the Controll XG coverstock – a blend of urethane and reactive chemistry – and is therefore aimed at drier lane conditions. Within Storm's related !Q Tour line, which uses the same core, the Sword Prime positions itself closest to the !Q Tour Fusion by Storm and the !Q Tour Pink by Storm, both of which work with R2S Hybrid coverstock at a 1500 polished finish and could therefore react to friction somewhat earlier by comparison. The Electrify Hybrid by Storm with its Circuit Core (2.510 RG, 0.030 diff) and likewise Reactor Hybrid coverstock represents another close comparison ball, although the Circuit Core has a somewhat different mass distribution than the C³. In the broader market you can also draw parallels to the Venom Toxin by Motiv (Atomix HR Hybrid, Gear Core, 2.480 RG, 0.034 diff) or the Brute Strength by Brunswick (Savvy Hook Hybrid, Brute Core, 2.491 RG, 0.032 diff), both of which sit in a similar performance segment for medium lane conditions.
On the Lanes
The Storm Sword Prime should perform best on light to medium oil conditions. The polished 2000 hybrid reactive cover should give the ball enough length through the heads to then react to friction in a controlled manner in the midlane. The low differential at 15 pounds (0.029) points to a rather limited flare potential, which could contribute to a predictable, arcing ball motion without overly angular changes of direction. That characteristic makes the ball potentially interesting if you value controllability and predictability – strokers and tweeners in particular should benefit from the smooth, even transition at the breakpoint. Crankers with a high rev rate could use the ball as a complement for lighter conditions or as a transition ball when the lanes dry up over the course of a block. The C³ Centripetal Control Core is known for revving up quickly while producing a smooth change of direction – a combination that should provide good carry in the pocket especially on house shots with a typical oil pattern. As an overseas release, the Sword Prime is particularly suited to the Asian and European markets, where it is positioned as a versatile all-rounder in the mid performance segment. It could be a sensible addition to your arsenal if you need a controllable ball to start a block or for shorter oil patterns, one that neither reads too aggressively in the heads nor overreacts on the backend. The polished surface can be sanded down if needed to get more early reaction, which gives the ball additional flexibility in adapting to different lane conditions.
