reach of the LHC to discover RS through its detection [@Agashe:2006hk].

While the KK gluon is the most promising avenue to discover RS, it is nevertheless challenging. The coupling to the light quarks that are the primary constituent of the proton, while characterized by the strong coupling, are somewhat suppressed by the localization of the light fermions close to the UV boundary (in the CFT language, the light fermions are largely fundamental fields and couple to the gluon largely through a small mixing with CFT states). This leads to somewhat smaller production cross sections than are typical of QCD. The decay of the gluon is expected to be predominantly into top quarks, a consequence of the large top mass, which necessitates that top is itself located close to the IR brane (mostly composite). The tops are produced from a very heavy resonance, and are highly boosted, which makes it experimentally challenging to reconstruct them from the large QCD backgrounds [@Agashe:2006hk].

In this article, we explore several more of the commonly considered theories which attempt to render RS consistent with precision electroweak data. We consider the model with a simple $SU(2)$ [@Agashe:2003zs] custodial symmetry (already studied before [@Agashe:2006hk]) as a beginning,
