To push or not to push, that is the question

Villain here is total maniac, betting the pot >50% of the time, pushing his stack and reloading. This is Pot Limit Omaha Hi/Lo 8 ... Maniac is on the button, I'm late MP, SB is an OK player.

I have A [img]/images/graemlins/spade.gif[/img] A [img]/images/graemlins/diamond.gif[/img] 4 [img]/images/graemlins/heart.gif[/img] 9 [img]/images/graemlins/club.gif[/img]

Maniac only calls on the pre-flop, which goes round 8-ways for $2 apiece.

FLOP - A [img]/images/graemlins/heart.gif[/img] 5 [img]/images/graemlins/club.gif[/img] K [img]/images/graemlins/club.gif[/img]

UTG bets ($2), UTG+1 calls, MP calls, MP+1 calls, Hero raises to $28 (bets pot), CO folds, Maniac raises to $108, SB calls ($106), fold, fold fold

Hero has $69 left. Easy push? Was the pot bet OK? Straight unlikely, Ax [img]/images/graemlins/club.gif[/img] would probably call... I knew that Maniac would call/raise, I didn't know about the SB.

I guess with $230 in the pot it's an easy push, but I suppose was the $28 pot bet worth it? anyone? [img]/images/graemlins/smile.gif[/img]
