  We compute Z-factors for general staggered bilinears on fine (a \approx 0.09
fm) MILC ensembles using both asqtad and HYP-smeared valence actions, comparing
the results to the predictions of one-loop perturbation theory. This is an
extension of previous work on the coarse (a \approx 0.12 fm) MILC ensembles. It
provides a laboratory for studying NPR methodology in the staggered context,
and is an important stepping stone for fully non-perturbative matching factors
in ongoing computations of B_K and other weak matrix elements. We also
implement non-exceptional RI/SMOM renormalization conditions using the asqtad
action and present first results.
