Who is favored here?

[Redmen62]

This is from a PL Omaha Hi hand from a home game this evening.

I'm holding A [img]/images/graemlins/diamond.gif[/img]A [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]2 [img]/images/graemlins/club.gif[/img]

My opponent is holding 6 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/club.gif[/img]8 [img]/images/graemlins/heart.gif[/img]9 [img]/images/graemlins/club.gif[/img]

The flop is: A [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/club.gif[/img]

Who is favored on the flop? We debated at the time about who was a favorite at the time, but there's no question I'd rather have my top set vs. his flush/straight/dominated full house draw. Hopefully some of the number-crunchers can weigh-in here...
