Casey, the Albastache is 55.5cm wide, the Alba and the Choco are 55cm. The sweep angles of the Alba and Choco are the also same . The difference between the bars is the drop and forward extension, the Choco being less in each. It is as Riv says "the Alba with a few tweaks" .
Your third photo in your first post , with just the 2 bare bars pretty much depicts this ! Well done !
There is a flickr image of Riv bars superimposed on each other, I suspect this will be added soon.

The Bar on Bar shot is the Albastache not the Albatross. So yeah, it is totally wider.
