Well I can't think of any other good Water pokemon that I'll likely pick up, and I actually don't like Vaporeon. I think I used him once in Gale of Darkness but I then used my other memory card on my GC and got Jolteon instead so really the only Eeveelutions I use are Espeon and Jolteon. I like Espeon mainly because of his high SP Attack and Speed. I think I'll train him up, give him the quick claw and hope for the best in the next gym, with Confusion being super effective on poison or something. Quilava should be good enough anyway. And then Togetic also knows Extrasensory so I could always use him as well, since it will also render any ghost moves useless.
