Abstract The empirical equality of B$sup 2$/sigma/sub t/ is noted for the pomeron terms in NN, $pi$N, KN, rhoN, $omega$N, and phiN scattering, where B is the elastic slope parameter and sigma/sub t/ is the total cross section. This ratio increases slowly with energy, but remains the same in all channels. This is equivalent to a relation between the diffractive interaction radii and opacities; the opacity scales with the square of the radius. It is conjectured that this systematics extends to psiN scattering. B$sup 2$/sigma/sub t/ universality is contrasted with the slope predictions of an f-coupled pomeron model. Some other predictions of the f-dominance hypothesis are tested against data. (NL)
