Popis: Relations betweens-channel helicity amplitudes implied, in an exchange model, by parity andG-parity conservation at each vertex, are derived. This allows us to formulate high-energy exchange models in terms of direct-channel amplitudes. In the framework of the Reggepole model the effects of «evasive» and «conspiratorial» solutions are examined and visualized on experimentally accessible quantities. It is shown that a solution which would be «conspiratorial» in all processes involving particles with arbitrarily large spins is very unlikely since it would imply that particles have no definite parity.
