  One can expect accessible lower bounds for dark matter detection rate due to
restrictions on masses of the SUSY-partners. To explore this correlation one
needs a new-generation large-mass detector. The absolute lower bound for
detection rate can naturally be due to spin-dependent interaction. Aimed at
detecting dark matter with sensitivity higher than $10^{-5}$ event/day/kg an
experiment should have a non-zero-spin target. Perhaps, the best is to create a
GENIUS-like detector with both Ge-73 (high spin) and Ge-76 nuclei.
