Apparently, from what has been previously discussed here, not all the
8-pole filters are "no offset" in practice and some models in particular
might benefit from offset adjustments. And one should not forget that
these filters are roofers. Unless money is no object, I would say to
leave the stock filter in place and add another, narrower SSB filter. As
to what its BW should be, there have been scads of opinions expressed on
that subject, as well.
