[omaha hi lo king]

So i am beginning to play on omaha split. who are the top players on the site at 2/4 no/pot limit and 5/10 nl/pl. i hear there are a lot of donkeys who are the players i should not call an all in against. Who are the top players to talk to on there for strategy. i have watched some games and some guy named IDIOT and PREDATOR seem to go all in preflop at least 1 out of every 5 hands. Seems like there are others following this style. some advice?
