Once you play your Herbert through EVM12Ls or EVM12L BLs, v30s reputation will permanently be damaged. I can't begin or end telling you how much ass they kick with Herbert particularly & never sound bad with any amp head. Your excitement will double once you get on a stage with them. EVMs are so much more on stage than they are in studio or home playing.
With that said, IMO, 4 BL EVMs are overkill, unless you play on big stages. I'd go with X pattern with something else. Did I mention they are too heavy?
For a 2x12 one classic & one black label should be fine in any situation. Shit, I hook up my BL to my bass rig as an extension cabinet. I wouldn't recommend doing this to anyone else though.
