Depends on what character you're after, but next to the Holy Diver you could consider the Abraxas too. It's has more PAF-flavour, but good output, fat mids though balanced tonespectrum, great cleans and it will do nice in a bolt-on alder-guitar. The uberversion of that, the Crawler, excels in bolt-on guitars. It has more a bit more compression then the Abraxas. It growls really nice when driven. Solotones never get shrill.
The RY in alder is always a bit risky bec of the bright topend and it's quite heightsensitive. A Nailbomb could do too, it's more agressive then the centermid focussed, creamy HD, has more bass, a uppermid peak and more treble. My choice would HD, Abraxas or Crawler.
