The implications of duality and absence of exotics are investigated in a multiperipheral model of pseudoscalar meson-meson scattering. An exchange-degenerate leading trajectory is obtained besides low lying ones in exotic and non-exotic channels. The absence of resonances with exotic quantum numbers
