The highly chiral nature of the couplings of $g^1$ to top, bottom, or the custodial partners may be visible as an observable [@Agashe:2006hk]. The top final state is particularly promising, because the left-handed nature of the $W$-$t$-$b$ interaction implies that the top decay automatically analyzes its production polarization. For example, the standard RS scenario has about $95\%$ decays into right-polarized tops, whereas the model with $\kappa r_{IR} = 10$ has roughly equal decays into left- and right-polarized tops, and the model with expanded custodial symmetry with $Q_3$ localized at the IR brane has about $99\%$ decays into left-polarized tops.

Finally, given the large cross-sections, it is natural to ask what the current bounds from the Tevataron on anomalous top production imply for the KK gluon mass. A recent analysis from CDF [@tevbound] has set bounds on narrow resonances in the $t\bar t$ invariant mass spectrum. While the analysis does
