These asymmetries have been shown to be particularly sensitive to graviton or other spin-2, s-channel exchanges in the process e[sup+]e[sup -][yields] f[bar f] (F[ne] e) which allows for a doubling of the usual search reach. A question then arises as to whether other e[sup+]e[sup -] processes also show comparable sensitivity. Here we extend our previous analysis to the set of final states e[sup+]e[sup -], W[sup+]W[sup -], 2[gamma] and 2Z as well as to the Moeller scattering process e[sup -]e[sup -]. We demonstrate that these reactions yield transverse polarization asymmetries which are somewhat less sensitive to graviton exchange than are those obtained in our earlier analysis for e[sup+]e[sup -][yields] f[bar f].
