We examine the optimization of the NLC for e{sup -}e{sup -} running. The dependence of luminosity on the interaction point beta functions {beta}{sub x}, {beta}{sub y}, emittances {epsilon}{sub x}, {epsilon}{sub y}, bunch charge N, and bunch length {sigma}{sub z} are very different for e{sup +}e{sup -} and e{sup -}e{sup -} because disruption reduces the luminosity in e{sup -}e{sup -} rather than increasing it as in e{sup +}e{sup -}. We examine how much luminosity may be regained in e{sup -}e{sup -} by varying these parameters away from optimized flat beam e{sup +}e{sup -} values. The results are compared with round beam e{sup -}e{sup -} designs considered in an earlier paper.
