Quasi-eikonal and quasi-U-matrix unitarization of the standard Regge-pole amplitude for α(0)>1 have been considered. We show that some violation of unitarity even at high energy exists in both models. We have found in quasi-eikonal model a bump-oscillation structure of \rm ImH(s,b) at large values of impact parameter b but where \rm ImH(s,b) is closed to the maximal value. We argue that it is possible to choose the parameter regulating deviation of generalized models from pure eikonal or U-matrix modes in order to restore unitarity.
