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

Compare Wall Wedge 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.
