I sent you a detailed PM, but in short, it's just not quite "metal" enough for my needs. That said, if you like the real Bogner Shiva, chances are you'll like the Shiver.
As for trades, I'm looking for something in the "modern heavy" vein, such as an Angel, Chupacabra, Mr. Boga, Benzin, Mamba, or Voodoo Sear (probably plus cash for the latter). Other than the Boga, I've owned and enjoyed all of those in the past.
I should also note that I don't have to ability to run dual modules, so those are probably out as well.
