Under-full, too much action?

Hi everyone,

I've been lurking on these forums for quite a while, and I figured it was time to start contributing and posting some hands. This hand happened in a live 3/6 game; I'm wondering what you put both villains on, and if you call the river:

10-Handed Live 3/6, $500 max buy-in

Hero has a fairly tight image. I've never seen either villain before, but Villain 1 seems weak-tight, and hasn't played a hand in about an hour; Villain 2 is playing fairly LAG.

Villian 1 ($880) limps UTG, Villain 2 (covers) limps in LP, Hero ($1400) limps on Button with 44. 5 way to flop.

FLOP ($30): J [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/spade.gif[/img]

All check to hero, hero bets $30, both villains call.

TURN ($120): 8 [img]/images/graemlins/diamond.gif[/img]

Both check, hero bets $100, both call.

RIVER: ($320): J [img]/images/graemlins/spade.gif[/img]

Villain 1 moves all-in for about $750, Villain 2 calls. Hero ???
