We find that as expected, the rate for the model with custodial symmetry is enhanced by the large bottom coupling by about an order of magnitude. In addition, the model with IR boundary kinetic terms shows a rate which is suppressed by a factor of about five, because while the boundary kinetic term slightly enhances the coupling of the UV-localized $b_R$, it more dramatically suppresses the coupling to the IR-localized $b_L$ (c.f. Figure \[fig:gffbkcoup\]). Ultimately, one must include the SM background and detector efficiencies for a specific decay channel of $g^1$. As a step in this direction, in Figure \[fig:diffcrosplot\] we plot the differential cross-section for both the $pp \to t\bar t$ and $pp \to b t\bar t$ signals and SM backgrounds with respect to the $t \bar{t}$ invariant mass, in the standard RS model and one with a larger custodial symmetry. In both cases, for $M_{g^1} = 2$ TeV, a peak is visible above the SM background, and the size of $g^1 b$ production relative to $g^1$ production discriminates between the two models.
