I got the Mesa Vertical 2x12 as well, but I swapped the top V30 out for a G12-65 Heritage, to soften the highs.
Another great combo would be the V30 with an old (serifed font label, vented or non-vented) T75 on top. Which basically is a G12-65 with a different former material. Only the later T75's (say from '88 onward...rough guess) were the fizzy and scooped, muddy hot mess. But those older ones sound glorious
