At the begining i usually go to Rockers/Popos, then Wolves which all are not rly worth to be double exped. Then i'd go to Les, Neko Island, HWs, probably Geos. Spores are somewhere between Popos and Wolves, so aren't that great to be the monster of the moment too. Something of Les, Nekorings/Leafcats, HWs or Geos might be more usefull. But whatever, i'm not going to start any new characters in the nearest future, so thanks for sleepers ;P
