Our first observation was that our bootstrap condition implied, for the scattering of S U (3) q¯q-compounds, a degeneracy of the exchange degenerate q - f, ω - A2 trajectories. This conclusion holds for a large variety of dynamical models and remained to hold when S U (3) was broken. We then included a quark-spin and showed that, because of the appearance of degenerate ghost trajectories, a consistent bootstrap scheme could not be formulated. Generalized to linear trajectories, a nice feature of the model was the absense of tachyons.
