Lightest FSA ACR-Compatible 2-Piece 36/38 Aero Cockpit

[wintermute]

I appreciate I could pick up a Lexon Unno or Vero one-piece, or an Avian Falcon or spend some more for a Farspots F1, but if I wanted to put together a two piece cockpit that's light and still allows me to clip on aero bars for long-distance bike touring / racing, what would you use?

Needs to be compatible with FSA ACR internal routing (the stock ACR stem is like 250g!)
