Black Bull. He's got the best snaking in the game due to Sega's genious weight distribution in the machines his being mostly in the back. And since he isn't stiff when played advanced, he actually far more easier to control than normal. His heavy weight also makes his MT boosting a bit better. He goes a bit further and it doesn't take much to get him flying. You can skip HUGE portions of BB Ordeal much easier as opposed to say Falcon. I only use Bull. Master class? lol It's a lot like Hellfire's "Phantom Elite My Arse" vids when I play. xD
Ironically, I suck at WipEout.
