  We study to what extent a measurement of the $m_\bot$ spectra for hadrons and
their resonances can resolve ambiguities in statistical model description of
particle production. We describe in quantitative analysis how physical
assumptions about the freeze-out geometry and dynamics influence the particle
spectra. Considering ratios of $m_\bot$ distribution of resonance-particle
ratios (such as $K^*/K$, $\Sigma^*/\Lambda, \eta'/\eta$) we observe significant
sensitivity to fireball freeze-out geometry and flow dynamics.
