Mercury Anubius Red 85XF is owned by the character Yuki Mizusawa. Its Spin Track is a top tier. Xtreme Flat is the second widest Flat Performance Tip currently available (first being GF). Xtreme Flat has fast and aggressive movement, equal to that of Right Rubber Flat. Xtreme Flat is a great Performance Tip for Attack Type Beyblades, and is top-tier at that.
