I play through a QR 50 watter and a 2x12 cab. Couldn't be happier with the Creamback M65's I loaded my 2x12 with.
Scott Splawn also likes them himself.
The 55Hz G12H30's are pure thick and smooth, as are the G12-65's. But after a stint of using 2x 70th Anniv's in a 2x12, and then swapping out one of them for a V30 faired better, but not as good as a G12K85+V30 mix.
