I'll try it soon but i think you're right.

Talons junction boost barrel roll start on venom and a bad example on phantom. Works on flash too, but i just couldn't manage it on rapier.
Wow! Good find. That will affect the speed lap times lol . I didn't know that pitching up, down then up again got you an extra bit of air .
