  A simple constituent model of gluodynamics that is motivated by lattice field
theory and the QCD Hamiltonian in Coulomb gauge is applied to descriptions of
hybrid meson flavor mixing and vector hybrid configuration mixing. Good
agreement with lattice gauge computations is obtained for flavor multiplet
masses, while mixing angles are in approximate agreement, given large errors.
The configuration mixing results are also in rough agreement with lattice NRQCD
calculations. Thus the viability of constituent gluon models of hybrid hadrons
and glueballs is supported. The results suggest that a flavor multiplet of
vector hybrids should appear with masses of approximately 2100, 2200, and 2300
MeV and that the isovector vector hybrid decay constant is about 20 MeV.
Similarly, the $\pi_1$ exotic hybrid should have isospin partner states near
1760 and 1900 MeV, and it is suggested that the recently seen $\eta_1$ hybrid
signal is the latter state.
