  We compare the fully nonlinear and perturbative evolution of nonrotating
black holes with odd-parity distortions utilizing the perturbative results to
interpret the nonlinear results. This introduction of the second polarization
(odd-parity) mode of the system, and the systematic use of combined techniques
brings us closer to the goal of studying more complicated systems like
distorted, rotating black holes, such as those formed in the final inspiral
stage of two black holes. The nonlinear evolutions are performed with the 3D
parallel code for Numerical Relativity, {Cactus}, and an independent
axisymmetric code, {Magor}. The linearized calculation is performed in two
ways: (a) We treat the system as a metric perturbation on Schwarzschild, using
the Regge-Wheeler equation to obtain the waveforms produced. (b) We treat the
system as a curvature perturbation of a Kerr black hole (but here restricted to
the case of vanishing rotation parameter a) and evolve it with the Teukolsky
equation The comparisons of the waveforms obtained show an excellent agreement
in all cases.
