Sparkling Attacker
Not to be confused with Spark Knight
AKA: Sparking Attacker (typo)
Weight: 5.3g (Core Part: 1.6g | Outer Part: 3.7g)
Right Spin only
Considered a single part (similar to Dual Dragon) and the centre part does not have the same width and depth as SAR-compatible ARs, meaning it does not fit with most of them even if it were legal, and in many cases poses a disassembly risk. As a result of this it must also be used with both parts.
Small inner section encased in a semi-free-spinning (free spinning but with significant friction) outer shell.
Takara version has a flint/sandpaper based spark gimmick. Hasbro's doesn't. This makes the Hasbro version marginally, but not significantly, more effective.
A fully free spinning Attack Ring may seem useful, but Spark Attack Ring's implementation is not very effective.
Too much friction for free-spin to be worthwhile, with or without spark gimmick
Design of outer part is far too recoil-laden to be competitive even with the semi-free spin gimmick.
Can be used as an option for defensive combinations, however it is heavily outclassed by a huge number of alternatives, including the readily available Roller Defense Ring
Small Size does allow some use for Right Spin Zombie and Defensive Zombie customizations, however as it loses speed the outer ring tends to go off centre, causing balance issues. It remains an acceptable choice, but not a top-tier one.
Thin plastic sections on underside of outer part break easily
Not Competitive
Weight: 15.3g
The most compact weight distribution of any weight disk.
It is worth noting that there is quite a broad range of weights for this Weight Disk, which one should be wary of.
The large corners of its shape result in some recoil when hit, though its compact weight distribution provides some protection against this.
Ten Heavy outclasses it slightly in all aspects of performance due to heavier weight, lower recoil, and Eight Heavy is marginally heavier, with a slightly less compact distribution making it a viable alternative.
Fairly competitive in Compacts and Traditional Upper Attack and a backup choice for Weight-Based Defense and Semi Flat Base Stamina Combos.
Weight: 6.5g
Right Spin Only (Built in Spin Gear)
Very low height allows it to get under things but lack of compatibility with an Heavy Metal Core removes any use for Traditional Upper Attack.
Limited recoil control due to light weight and poor grip.
Somewhat difficult to flower pattern.
Decent LAD means it can be used to some effect similarly to a Semi-Flat Base Stamina setup, though due to its aggression it makes better use of Wide Defense - a viable setup would be this and a Compact or smaller-sized Defensive AR.
While this is not that competitive a setup, it is able to outspin a surprising number of opponents and KO weaker combos, thus giving Flat Base some semblance of use.
Overall not a great part, but usable.
Overall
Unfortunately due to the poor execution of the AR gimmick, it is far less useful than it may seem at first glace, and as such Sparkling Attacker is best left for collection purposes though the Takara Version's gimmick is quite enjoyable in the dark.
