Eevee evo

Hey all,
I need your opinion on that. I caught a lv 27 84% eevee (14hp/ 12/12) and thinking about what evolution to seek. Right now, I have 2 excellent vaporeons that I have maxed (and a few more less strong just in case I need more caps, but the truth is that I be never used them). I also have also 2 high IV jolteons but none with thunderbolt. One with discarge and one with thunder. I have 2 more with thunderbold but lower IV and around 2100cp, I dont power them up just use them.

I don't have any fs/oh flareon but the truth is I need none. I have 4-5 excellent arcanines and a high IV e/fb flareon, I really don't need other fire fighter.

Now, I haven't used the name trick for both espeon and umbreon. The truth is I feel they are worthless. I have a lv 30 91% alakazam with pc/fs so espeon is probably almost the same(right?). And umbreon, what's the use of it? As a prestiger? Against what?

Sorry for the long post and thank you for your time. If you were me, what would you do?
