Playing a set of aces on an all-low board, $25 PLO8

[T50_Omaha8]

$.10/$.25 PLO8 6-max with a $10 cap, meaning after betting a total of $10, a player is considered all-in. Just played the table through an absurdly loose and profitable hundred hands, but most of the idiots had gone and things were a little tighter now. 4 handed, everyone has the cap covered, and BB is pretty awful.

I'm dealt A[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/heart.gif[/img] in the SB.
2 limps to me, I call, BB checks.

Flop: A[img]/images/graemlins/heart.gif[/img] 8[img]/images/graemlins/heart.gif[/img] 7[img]/images/graemlins/spade.gif[/img]
I check, BB bets $.50, UTG raises to $1, Button calls, Hero ???

What if the board is rainbow? What if the board is Ah8h9s? A89 rainbow?
