Absolutely torn in X and Y

Okay, so I'm doing yet another run-through of Pokemon Y. Currently in my team, I have Quilladin, Pidgeotto, Vespiquen, and Litleo. I know I need a pokemon with the ability to use surf, and I'd really like to use Dragalge. Though, I'm torn between my last two mons. I want to use a Reuniclus and a Jolteon, but I don't want to get rid of Vespiquen (seeing as that's the only option if I want to keep a pokemon that can learn fly, like pidgeotto). Just help me decide!

Vespiquen can't learn Fly. So you could take it off your team so that you can fit both Reuniclus and Jolteon in your team. If you don't want to replace Vespiquen, you could replace Pidgeotto instead. If you don't want that either, you should just go with Reuniclus.
