  We apply a generalized spin-basis analysis to associated Higgs production and
gauge boson pair production at LEP. This framework allows us to identify a
choice of spin axes for the processes e+ e- --> ZH,ZZ which leads to strikingly
different correlations among the decay products, even well above threshold.
This spin basis optimizes the difference in the angular correlations for these
two processes. In contrast, the same distributions display little contrast when
the helicity basis is used. We also apply this technique to the case of W boson
pair production.
