  We explore the phase structure induced by closed string tachyon condensation
of toric nonsupersymmetric conifold-like singularities described by an integral
charge matrix $Q=(n_1 n_2 -n_3 -n_4), n_i>0, \sum_i Q_i\neq 0$, initiated in
hep-th/0510104. Using gauged linear sigma model renormalization group flows and
toric geometry techniques, we see a cascade-like phase structure containing
decays to lower order conifold-like singularities, including in particular the
supersymmetric conifold and the $Y^{pq}$ spaces. This structure is consistent
with the Type II GSO projection obtained previously for these singularities.
Transitions between the various phases of these geometries include flips and
flops.
