For years the standard for 3A design has been stability and spin power, but Yoyorecreation and Takimoto aimed to create a 3A design with a more nimble feel in play. The RAMI is a bi-metal design with an aluminum body and Stainless steel rings that extend to compose the outer edge of the profile. It has quick maneuverable feel in play with enough power for the most dynamic routines.
I notice that this cup design has sorta become YYR’s standard for recent releases: Overdrive Draupnir, Inevitable, and now the RAMI. Don’t get me wrong, I love this cup design, but it does kinda make them hard to tell apart at a glance.
