Abstract
A U(6)-symmetric Regge-pole model with explicit quark spin is applied to meson and baryon exchange in the $\ensuremath{\pi}N$ system. Attention is focused on the general form of the polynomial residues which result from including the required projection operators. Detailed calculations are exhibited for forward charge-exchange scattering within the context of a dual model with fixed cuts. For the case of baryon exchange a Regge residue appropriate to the symmetric-quark-model spectrum is presented and studied.
