"Who do you guys think I should walk with next?"

#PokemonGO: I've been walking with Shieldon for a few weeks now, and finally have enough candy to evolve him. Once I do that, I will have every Pokemon currently available, with the exception of regionals and a couple of legendaries I missed.The last time I was in this position, I had just finished Gen 1 and Gen 2, and we were still a few months away from Gen 3 dropping. So in the meantime, I started walking with things like Togetic, Rhyhorn, and other Pokemon that I knew I would be able to evolve once Gen 4 hit.But what do I walk with now? I don't do a ton of raiding because I live in a small town - I take a train to a nearby city once a month when a new 5 star boss shows up, but those groups are so big and powerful it kind of doesn't matter how powerful my legendaries are. But should I?I'd love to hear everyone's thoughts on this. Thanks guys! via /r/pokemongo http://bit.ly/2E5oUJv
