I've been having pretty good success with this Centurion build:
CN9-A(C) STD275
You sacrifice firepower for speed but it works well enough as a second-line 'fireman'; run around and give fire support to engaged teammates.
Alternatively, you can mount a LFE275, carry more ammo and swap one or both ML's for MPL's.
CN9-A(C) LFE275 MPL
They will go even faster with speed nodes unlocked.
Good hunting,
