You know, I've had problems with the "Zig-Zag" idea too. I've tried to work with it with varying degrees of success. It seems mostly dependent on the other pilot's skill. Basically, if they have any, I get toasted.
While Jousting, try to strafe in all directions, it's harder to aim, but makes you extremely hard to hit. If you're up for some sparring, I'm always down. PM me just in case I happen to loose track of this thread.
Heh, and let me know if you get that Zig thing down.
