O8 SNGs, endgames

I've only been playing omaha for a month, and i've only played 30 or so sit and go tourneys. i've been doing fairly well so far (70% ROI) though I know the stats mean nothing at this point. anyway, does anyone know where i can find some advice on how to loosen up the game with 5 and less players left? how does hand selection change? which flops look more appealing compared to the same kinds of hands with a full table? the search engine on here hasn't brought me anything, so i'd appreciate a point in a favorable direction.
