One other point about those 2hp VCAs: you have no mixbus between them. If you go with things such as Happy Nerding's 3XVCA or Mutable's Veils or Intellijel's Quad VCA, you ALSO get a mixer thrown in for "free". And this can come in handy quite often; fact is, you should always try and look for additional functionality whenever possible, as this ups the build's capabilities while keeping the "sprawl" down.
