Arcadi and Del Balso are most likely still allied with the Rizzutos. This may simply be Leonardo and Sollecito's inner core of friends and business associates. Most on that list have crews of their own that are in effect stil part of that group. I don't think these people do the collecting, enforcing and killings themselves.
The Rizzuto cell are also mostly Sicilians except the Sollecitos, while those Acardi-Del Balso guys are mostly Calabrian.
