We argue that a new strong force which induces electroweak symmetry breaking via top condensation presumably leads to a rich t−t bound-state spectrum composed of more than the three Goldstone boson and one Higgs mode. We discuss the dynamical consistency conditions for the enlarged t−t bound-state spectrum and demonstrate how top mass predictions change when the effects of such an enlarged spectrum on the generalized compositeness conditions are included. It is found that these corrections can be bigger than the corrections found in two-Higgs and supersymmetric generalizations of the minimal mechanism. As a consequence it is possible to obtain a phenomenologically acceptable top mass.
