  We present some results pertaining to partially quenched formulations of the
overlap/domain wall operator with the Thirring model in 2+1D. Auxiliary fields
are generated with a Shamir domain wall approach and measurements of
eigenvalues and condensates are contrasted with different overlap operators.
The numerical challenge posed by a non-compact formulation is highlighted, and
the effective use of lower accuracy sea fermions is demonstrated.
