Planar unitarization of dual models is examined in terms of renormalized diagrams. The shift of the Reggeon intercept 1 - α(0) and the renormalized coupling g2N 16π are both expected of order unity in a model with SU(N) Chan-Paton factors. In four space-time dimensions Regge behaviour makes the shift of the dual photon mass reminiscent of Schwinger's mechanism.
