  We study probe flavor branes supersymmetrically embedded in the
Klebanov-Strassler background. The embedding is controlled by a single complex
parameter mu related to the quark mass. We study the spectrum of the vector
mesons as a function of mu and compare it with the experimental data. Assuming
that the rho(2150) meson is a 3S mode we find a remarkable agreement with the
masses of the lightest excited rho-mesons. Also, for a certain range of
parameters our model exhibits an unusual behavior. The mesons built of the
lighter quarks become more heavy than the ones built of the heavier quarks. We
comment on a possible connection this phenomenon may have with the masses of
the putative pure strange-anti strange mesons.
