Vaporeon Blues

Completely disagree.
Diversity is the name of the game. Build up different mons and teams, attack with some variety, and leave some randoms in gyms. It's completely boring and lame to me to have an army of Vaporeons.
I have 5 Vaporeons per the "rule" I said above. None ever occupy a single gym and I am currently holding 16 gyms in So Cal.
You do not need an army of Vaps. It's overkill, lame, and par for the course.
I have just stopped evolving them because don't even need more, I have 13, 10 of them with Hydro Pump, 6 with more than 2500 CP and 2 maxed out at my level (33) the lower ones I use for prestige gyms, but even with that I am at 890 eevee candies and have 10 eevee with 90%+IV waiting for next gen's.
A part from pidgey, rattata, caterpie, weedle, zubat and rest of the crap eevee is by far the most common spawn for me.
I agree it's time to start trimming the fat. Only keep an amount that's a certain IV or above and trash the rest. Like my rule is 88%+ and A rated move set. Keeping a minimum of 1 for atk and 1 for def the rest transferred unless I'm scarce on that mon. Vapes for example I have like 8 of them but none are below 88% IV. That's mainly because he's useful for offense or defense and all his moves are A rated. If the mons rating was poop like say electrode. I'd only keep 2 of the highest rated IVs with the best moveset for attack and def then transfer the rest.
My only other exception is 100% IV mons they can have the worst moveset available to them. I'll still keep them but I'll also have at least 1 other attack & at least 1 other defender
Edit: I still have 82%+ Eevees but those are for gen 2+ eevolutions until I get to a point where I'm trimming them down as well.
It doesn't seem like you have too many vaporeons to me. They are easy to acquire top tier defenders, and it looks like you are already using four of them in gyms. You wouldn't want to get rid of those. It's also nice to have a range of CP ones with hydro pump for prestiging gyms (the IVs on these ones don't matter), and your highest IV one with hydro pump fully powered up as an attacker.
