I have always been content to use Yggdrasil or Bifrost or Gungnir in the first reference, and later in the article, I might refer to it as a Yggy or Bimby. I don't mind Bifrost 2, which seems like the Lincoln Continental Mark series.
The casual reference to weird abbreviations saves the reader or writer no time if it fails to communicate the name of the device. I like the Norse mythological references for naming, and I like Classic Silver metal, and I like the Schiit Sound.
So
@Jason Stoddard, if you call it 'Bifrost 2', that is the name I choose to use.
