  Isothermal models and other simple smooth models of dark matter halos of
gravitational lenses often predict a dimensionless time delay $H_0\Delta t$
much too small to be comfortable with the observed time delays $\Delta t$ and
the widely accepted $H_0$ value ($\sim 70$ km/s/Mpc). This conflict or crisis
of the CDM has been highlighted by several recent papers of Kochanek, who
claims that the standard value of $H_0$ favors a strangely small halo as
compact as the stellar light distribution with an overall nearly Keplerian
rotation curve. In an earlier paper (Paper I, astro-ph/0209191) we argue that
this is not necessarily the case, at least in a perfectly symmetrical Einstein
cross system. Here we introduce a {\it new mass degeneracy} of lens systems to
give a counter example to Kochanek's claims. We fit the time delay and image
positions in the quadruple image system PG1115+080. Equally good fits are found
between lens models with flat vs. Keplerian rotation curves. Time delays in
both types of models can be fit with the standard value of $H_0$. We
demonstrate that it may still be problematic to constrain the size of lens dark
halos even if the data image positions are accurately given and the cosmology
is precisely specified.
