I've got Rebel Yells in a Standard 22 and they sound awesome. No lack of balls for my money. I haven't used a Holy Diver, but I understand is has more low end, and less upper-mid and highs than the the Rebel Yell. That makes it quite in-yer-face for high gain, but not lacking in fatness IMO. I'm planning to do some clips soon.
If your guitar is dark, Tim usually recommends choosing a pickup with a higher resonant peak, which means lower output. I'm looking at Riff Raffs for my dark Les Paul, and they sound like they might be a good bet here. I don't know about Black Dogs, but since they are said to be quite fat without a huge amount of top end, they might sound dark in your guitar.
