I like Korina, based on the PRS McCarty Korinas I've played and owned. I still have one with Throbak PAFs in it and it's killer, second only to my Modern Eagle for humbucker tone.
If you're going to be putting high output pickups into the guitar, then the wood makes less of a difference to the overall tone for me. If you're looking at Mules or VHIIs, then they will let the subtleties of the wood choice come through. If you're looking at Painkillers or Warpigs then you'll mostly hear the pickup.
If you're playing metal, which I'm guessing you are, I would go with mahogany. It's cheaper and you won't get the benefit of the Korina's tone. If you were after classic rock or blues tones, I'd chose Korina.
Just my opinion, for what it's worth :)
