  We present flavour-symmetric results for the couplings of quark-antiquark
systems to meson-meson channels in the harmonic-oscillator expansion. We
tabulate their values for all possible open and closed decay channels of
pseudo-scalar, vector and scalar mesons. We compare the predictions of a model
that employs these flavour-symmetric couplings, both with the results of a
model which uses explicitly flavour-dependent couplings, and with experiment.
