What battle problem is Needle meant to solve?
Needle is mainly used for spin preservation and stable late-battle movement. Final performance depends on the Blade, Ratchet, stadium and launch.

Stamina
Start with Knight Shield 3-80 Needle; it is labelled as a official stock pairing with the note “Takara Tomy BX-53”. Compare it with Moff Gideon 3-80 Needle while keeping the Blade, stadium, launch and opponent consistent.

Compare Needle directly with the Ball Bit in the same complete build. Run at least five launches per side and record knockouts, bursts, self-knockouts, scraping and spin finishes; change only this one part.
Drop it if the extra spin time disappears once contact starts, or if it repeatedly loses the equal-spin and opposite-spin matchups assigned to it.
