Either the Stilleto or Oversized. Both are equally punchy, just a matter of where the bass is focused. What kind of sound are you going for?

Lots of great cabs out there though Soldano, Splawn, Rivera, Randall (the upper end ones), Fender EVH, etc.etc. Mesa is widely considered the standard in Heavy Music though, and not without reason.
What speakers have got got in your Marshall now, v30s or GT75s? What problem do you have with them?
