Weight Disk: Eight Wide
Weight (Hard Edge Mold): 12.7g
Weight (Soft Edge Mold): 12.2g
Very light weight
Two molds, one with sharper edges used exclusively by Takara, and one with softer edges used by both Hasbro and Takara (after production moved to China, presumably). The Hard Edge mold tends to be heavier on average but there is huge crossover between them and the difference can largely be considered negligible. The soft edge mold also often has bumps, generally smaller than those on Ten-Series Weight Disks, at one or both ends, which theoretically could make for poorer balance, though the impact is negligible.
Wide weight distribution, albeit less so than Ten Wide, Wide Defense and Wide Survivor.
Minor use with Attack AR's whose contact points are obscured by wider weight disks (eg Double Wing), though these limitations inherently render them inferior to many other options, and overall the lighter weight of Eight Wide leaves it outclassed.
