A model incorporating biquark and triquark Regge propagators in Reggeized supermultiplet theory is applied to some of the highest-energy meson-baryon charge-exchange data available. The fits are good within the limitations of the model and the standards prevalent in this field of phenomenology. Renormalization of some of the theoretical amplitudes improve the fits and indicates SU3 and SU6 breaking of about 10% in the residues.
