Finding an Edge in HU O8

Hi,
I've been experimenting with Heads up Limit O8 SnG's. I've found at the lower stakes that simply being able to fold "dead end" hands provides enough edge to win a good percentage of the matches. (I'm still working on not tilting [img]/images/graemlins/wink.gif[/img] )

Does anybody have experience HU, and have any advice to give? In particular, I'm trying to figure out the best approach to playing against LAG opponents. I hate just saying to myself "I could have the high or low, just call". I've tried being equally aggressive back but then the match can end in a heartbeat on a few pivitol hands.

I guess my question is, how do you play heads up against aggressive opponents? You know, those who will bet and RAISE with as little as an overpair or a decent low draw. Any other advice is greatly appreciated as well ...
