Guess I'll chime in a second time, this time on speakers. Played a SLO with V30s, 70s G12Hs, 70s G12Ms, and what must have been T75s.
T75s were harsh and scooped. Honestly could see it working for some types of metal, but my least favorite. Didn't like the G12Hs. Scooped and zingy high end. G12M and V30s sound awesome to me. Aggressive with plenty of bass and controlled high end. V30s have their obvious nasally voice, which I've always gotten along with fine, but the G12M would be my preference.
