Thank you for the reply. Anyways: My predictions for Heat D:

Whiplash (6) v Bladerunner X:

Depends. If Whiplash's blade keeps hitting Bladerunner on the tyre, then Bladerunner will outpush it. On the other hand, if it gets hit anywhere else, Whiplash will go to the heat final.

Mayhem (2) v Hit 'n' Run

Hit 'n' Run to make a surprise victory. It's invertible and rams, so yeah. It'll win.
