According to an interview with Dave Friedman he delivered 4x12 cabinets( when Dave worked for Andy Brauer's) with G12T75's and G1265's to 5150 studios when Ed was using the SLO and Dave says Ed preferred those speakers with the SLO.
SLO100 (not the 30) or 5150 would be my picks. If budget was a concern, 5150. To me, the SLO30 is not the same as the 100. I didn't like the overdrive channel on the 30.
