Second Fourier harmonics of jet quenching have been thoroughly explored in the literature and shown to be sensitive to the underlying jet path-length dependence of energy loss and the differences between the mean eccentricity predicted by Glauber and color glass condensate (CGC)/Kharzeev-Levin-Nardi (KLN) models of initial conditions. We compute the jet path-length dependence of energy-loss for higher azimuthal harmonics of jet-fragments in a generalized model of energy-loss for Relativistc Heavy Ion Collider energies and find, however, that even the high-p{sub T} second moment is most sensitive to the poorly known early time evolution during the first fm/c. Moreover, we demonstrate that higher-jet harmonics are remarkably insensitive to the initial conditions, while the different v{sub n}(N{sub part}) vs v{sub n}{sup I{sub AA}}(N{sub part}) correlations between the moments of monojet and dijet nuclear modifications factors remain a most sensitive probe to differentiate between Glauber and CGC/KLN initial state geometries of the strongly-coupled Quark-Gluon Plasma.
