Sorry to reply to this so late, but, IMO, the best way to use RBLs is:

a) do SBL and XBL at the MTA, so that you're NOT accepting ROKSO 
originating emails.

b) use those RBLs, plus any others you want to (RFC-Ignorant, etc.) in 
Spam Assassin to mark messages.


Step a reduces your SA load, and completely rejects messages that you 
can be better than 99% sure are spam.  Step b lets you leverage RBLs to 
help tag any other possible spam sources, but without outright 
rejecting them.
