An adaptation of the multispinor formalism for evaluating duality diagrams is applied to the scattering of mesons (6,6¯)(6, \bar 6) from baryons (56, 1). The prescription automatically provides the «correct»D/F ratios and relative magnitudes of helicity flip/no flip amplitudes at the particle poles, and reproduces Reggeized supermultiplet predictions in the asymptotic region. However, the resonance structure is highly unphysical and consequently the low-energy predictions are very poor.
