Heh, didn't a somewhat aggressive Basalt 230MS combo win a tournament last year? I was always puzzled by that one.
And just to clarify in case anyone asks (they usually do), obviously, those rulings follow common sense. Any tip will move aggressively with a Rev-Up launcher or Duo's Attack mode/M145, and there are a couple of launch techniques to get a few things to move aggressively, and obviously, that doesn't make the part illegal.
And yeah, it's weird how soft the metal they used for Driger S's tip was, though some of them almost acted like metal flats out of the box.
