  We present a systematic study of dijet suppression at RHIC using the VNI/BMS
parton cascade code. We examine the medium modification of the dijet asymmetry
$A_j$ and the energy distribution within the dijets. Understanding the
sensitivity of these observables to properties of the deconfined medium and to
experimental factors is vital if dijets are to be useful for QCD tomography.
VNI/BMS provides a controllable test-bed with sufficient complexity to model
jet modification without confounding results with fluctuations from
hydrodynamics and hadronization. Dijets are examined under the modification of:
the jet transport coefficient $\hat{q}$; the path length of leading and
sub-leading jets; jet cone angle and the jet-medium interaction mechanism. We
find that $A_j$ is very sensitive to the distance traveled by the secondary
jet, the jet shape is dominated by $\hat{q}$ and the nature of the interaction
mechanism.
