We present theoretical arguments toward the plausibility of a stellar wind to explain the 16,000 km s^–1 line broadening in the optical spectra of WS 35, the central star in the Pa 30 nebula. The wind model is discussed in the context of super-Eddington flows. We argue that WS 35 potentially occupies a new regime of wind driving theory as the first metal-only wind. This framework provides a promising avenue for explaining the high-speed flow. We further describe how future radio observations can provide an independent test of the spherical wind scenario. A magnetically channeled wind would likely produce a relatively flat and bright radio spectral energy distribution. By contrast, a spherical wind should result in a thermal radio spectrum with a canonical continuum slope of ν^0.6, and a brightness level consistent with the currently predicted mass-loss rate.
