In the context of Supersymmetry Phenomenology, adopting a bottom-up point of view and focussing on the lack of signals so far in the Higgs and in the flavour sectors, we argue in favour of giving consideration to supersymmetric extensions of the Standard Model where the lightest Higgs boson has a mass between 200 and 300 GeV and the first two generations of s-fermions are in the range of several TeV. This, in association with a pattern of flavour symmetry breaking centered on the special role of the top and up-type Yukawa couplings, leads to effective Minimal Flavour Violation of the Flavour Changing Neutral Current amplitudes. Moreover all the phases allowed by the flavour symmetry can be sizable without violating existing Electric Dipole Moment constraints, thus solving the SUSY CP problem. We believe that this view strengthens the case for hierarchical sfermions.
