  We systematically compare an event-by-event transport+viscous hydrodynamics
hybrid model to data from the RHIC beam energy scan using a general Bayesian
method. We demonstrate how the inclusion of multistrange hadron observables
affects the outcome of the Bayesian analysis and conduct an in depth analysis
of the viability of $\phi$ and $\Omega$ as probes of the transition region
between a deconfined quark-gluon plasma and hadronic phase in heavy ion
collisions at higher-end RHIC collision energies. Utilizing UrQMD to model the
final hadronic interactions, we examine the collision rates of $\phi$ and
$\Omega$ and the modification to their transverse momentum spectra due to these
interactions.
