raising in loose- passive pre-flop games

i have been wondering about this alot and i see very little specific advice out there about this.

it seems like so many of the no-limit games i play are pretty loose-passive before the flop.

i was wondering what hands people would raise with from the button and specifically the blinds.

the blinds seem very tricky. you act last before the flop but then you act last the next 3 rounds..... button is pretty straight-forward, although i find there isn't that much out there on no-limit loose-passive pre-flop games (which seem to proliferate). most advice seems to assume you are first to the pot.

has anyone given alot of thought to this? assume 4-5 callers.
