Hm, yeah, EV training is probably a better idea, then. Though yeah, stuff like Pomeg and Kelpsy berries reduce EV's in a certain stat already applied to a pokemon, though it takes a quite a few to reset them if you have trained the pokemon a lot. A Salon in B2's Join Avenue would help, though that gets expensive.
Yeah, as soon as I finish writing it up, I think a lot of my worries will disappear.
