I'm working on this design with the idea of hitting Deep-Sea Site 7 and a single end-game node in mind. My current build is a CUUU, but I feel it's hardly worth the mention due to the severe lack in the required Surveillance or Retrieval we're starting to figure we'll need (though it does sport a fast 100 Speed and 95 Range, working great for unlocking nodes on the cheap). Therefore, let me propose a different solution.
With the hopeful assumption that the Odder drops with a Surveillance rating equal to or less than 150, the CCSyC would be able to make a run from Deep-Sea Site 7 and a single end-game node (Stone Temple or Sunken Vault) in 2 days and 4 hours (just above a 2 day checkup). It also sports a decent 65 Retrieval and a large 140 Favor, possibly contributing a bit to the "luck" factor as well.
Route A: Deep-Sea Site 7 (W) > Sunken Vault (AD) (2 days, 2 hours, 24 minutes)
Route B: Deep-Sea Site 7 (W) > Stone Temple (AC) (2 days, 4 hours)
Route C: Sunken Vault (AD) > Stone Temple (AC) (2 days, 6 hours, 21 minutes)
