The MoRich Mania has a more dense "AWAKENING" Asymmetrical core for more hook and faster revving. From Morich "The Mania is designed for when you want all the hook you can get!"
The new "VIGOR" Pearl Reactive cover, in Purple Pearl/Blue Pearl/Red, is factory finished with 1000 Siaair surface. The "AWAKENING" Core creates a large flare potential with .051 Total Differential and Minimum RG of 2.486, producing a 6.3 second spin time. The .013 Intermediate Diff helps create a more angular break point.
