  The accuracy of effective chiral lagrangians including vector-mesons as
(hidden symmetry) gauge fields is shown to be improved by taking into account
SU(3)-breaking in the vector-meson sector. The masses, $M_V$, and couplings to
the photon field and pseudoscalar pairs, $f_{V\gamma}$ and $g_{VPP}$, are all
consistently described in terms of two parameters, which also fit the values
for the pseudoscalar decay-constants, $f_P$, and charge radii, $<r^2_P>$. The
description of the latter is further improved when working in the context of
chiral perturbation theory.
