  We use the non-normalizable complex deformations to describe the stringy
realizations of the metastable vacua in N = 1, SU(N_c) SUSY theories with N_f >
N_c massive fundamental flavors. The consideration of the non-normalizable
deformations requires a modified Toric duality. The new approach considers the
tachyon condensation between pairs of wrapped D5 branes and anti D5 branes and
the resulting mixing between some cycles in the geometry. We enlarge the class
of metastable vacua to the case of branes-antibranes wrapped on cycles of
deformed A_n singularities.
