I definitely prefer the VHII in this clip. Maybe it is just better suited to the guitar and amp you combined it with, but I disliked the low-mids in the Black Dog clips, although in the later section where these weren't so prominent I found them to be quite similar and I had no clear preference.
I don't know if you could adjust this out using the Resonance pot on the 5150 or not. If your amp was set up the same for both pickups that might be the issue, but then again on different settings we wouldn't have a good pickup comparison.
Cheers for the clip. It confirms my feeling that the two 'vintage hot' BKPs that appeal to me are the Emerald and VHII, rather than the Black Dog and Abraxas
