  To study galactic motions on the largest available scales, we require bulk
flow moments whose window functions have as narrow a peak as possible and
having as small an amplitude as possible outside the peak. Typically the
moments found using the maximum likelihood estimate weights do not meet these
criteria. We present a new method for calculating weights for moments that
essentially allow us to "design" the moment's window function, subject, of
course, to the distribution and uncertainties of the available data.
