Ev training tips?

Question

How can i make the most out of my ev training?

I ev train for defence on iron island (Diamond), my pokemon wears the belt and i battle dozens of graveler, but at the end, i often encounter a golbat,
should i run from it and look for another graveler or fight it?

Answer 1

It really depends on the pokemon as if you pokemon need speed too, then you should definitely fight it. If you don't then just run away.

Exactly as Rayquaza says. Unless you actually want Speed EVs on whatever Pokemon that is, run from every Golbat or find a spot that is consistent with Pokemon that give off Defense EVs.
