What is the smallest IPv6 advertisement that organizations are going to

Anything more specific than /32 is going to be filtered at some 
portion of the ISPs whether for the good or bad.  There are some 
subsets of the v6 address space that have a higher chance of /48 
working (for some definition of 'working') than other parts of the 
address space, though.

        perhaps you might better phrase this as; " Anything more specific
        than a /3 is going to be filtered at some portion of the ISPS whether
        for the good or bad."

        just because you have a prefix of (any) size, does not assure 
        that everyone will route it.
