Abstract
The t-dependent dual bootstrap scheme is studied in various cluster models in the j-plane. The importance of the analytic structure of the input amplitudes and proper counting of the contribution of intermediate states to the unitarity sum is shown. Certain counting procedures that correlate clusters and gaps in rapidity lead to integral equations which are not of the usual Chew-Goldberger-Low type. It is these counting procedures that may lead to a self-consistent bootstrap scheme (i.e. no cuts in the output amplitude). Some problems related to the roles of the reggeon-reggeon amplitudes, both in the planar bootstrap and in the calculation of the pomeron, are briefly discussed.
