We present the results of spectral fits to RXTE observations of GRS 1915+105 using the EQPAIR model of Coppi et al. (1999) to assess the effects of thermal and non-thermal Comptonization, as well as reflection. We note that such self-consistent models result in larger inner disk radii and lower disk temperatures than the previous fits using multicolor blackbody and power law models, thus solving the problem of inner disk radii at < ~ 1 Rsch. We also note that the major difference between the ``high" and ``low" states is the presence of a strong nonthermal spectral component in the low state and that the Compton y parameter remains fairly constant within the high state despite large variations in the optical depth and temperature. We discuss other observed correlations between the different fit parameters and consider possible implications for disk-jet interactions.
