I favor latest entry cataloging for serials.  Not because I think it's a
better way to catalog serials, but because that's the national standard
right now.
Unless your organization has unlimited funds/staff you cannot affore to
make a decision that my leave you in some backwater while the rest of
the library world maves forward in a new/innovative direction.  With
more and more of the serials process becoming automated, the need for
standardization of bib records and holdings records becomes more
pronounced.  If you're non-standard in the future, you may find that you
can't take advantage of new developments without costly programming.
