We use a principle component approach to contrast different kinds of probes
of dark energy, and to emphasize how an array of probes can work together to
constrain an arbitrary equation of state history w(z). Rather than using a
particular parameterization, we define a prior on the degree of smoothness of
w(z). We then examine how informative various experiments will be in
constraining the evolution of dark energy given different choices for the
prior.
