What battle problem is Flat meant to solve?
Flat is mainly used for aggressive movement and early knockout pressure. Final performance depends on the Blade, Ratchet, stadium and launch.

Attack
Start with Dran Sword 3-60 Flat; it is labelled as a reported tournament alternative with the note “24% of recorded podium builds · all-time”. Compare it with Venom 3-60 Flat while keeping the Blade, stadium, launch and opponent consistent.

Compare Flat directly with the Rush 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 movement produces more self-knockouts and early spin loss than clean knockouts. Record those outcomes separately over repeated launches.
