I'm usually a "run back to the center" person, but Mt. Coronet ruined that for me. Eventually I just get to the point where "damnit, I don't want to spend the time going back and forth fighting a million more (insert common pokémon here) so, fine, just have a lemonade already and shut up" and then it went downhill from there. :< But for regular routes I'm always running back and forth. Kind of envious of how well you remember the paths, though. I've always had a crappy memory and while it can sometimes be a good thing, usually it's not. >.>
