A naturally light Higgs can be realized as a PNGB. At low energiesit can be described by a 2-site model with non-linear σ-fields. There is freedom for composite fermion representations: we have considered the flavor phenomenology of fermions in 5 & 10 of SO(5). Naturalness allow for a splitting between resonances: gluon ∼ few × M _{W,ψ}, relaxing flavor bounds. Dipole constraints in anarchic models of flavor with a PNGB Higgs: FV dipoles require f > 0.5 TeV (0.7) for MCHM 10 (MCHM 5+5 ), FD dipoles require f > 2 − 4 TeV. As in non-PNGB Higgs, neutron EDM and CEDM introduce some tension with naturalness, independently of anarchy, for maximal violating phases. Anarchic scenario suggest that at LHC: gluon resonances will be out of reach, EW resonances are hard, very light fermions are allowed by FV dipoles. But FD dipoles, independently of anarchy, increase the fermion scale.
