History / About
LF stands for Light-weight Full-size. Per Yo-Yo Store Rewind it is lighter and larger than the original DoubleJoker, with a thick rim and wide pads for strong spin. It adds the Core Axle shared with the Luminous and Strider, and the response surface is tapered (higher on the inside, deeper on the outside) for a firm return with better slip. yoyo.fandom lists it as a 2011 variant with a KonKave bearing.
