Huge pot with heavy flop action

[pohuist]

20-40 live 10 handed. Very sweet game with several players playing close to 100% of the hands and calling the flop regardless of the number of bets with nothing. (Catching runner-runner every now and then).

UTG fish raises (his raises are solid while calls are not). 5 cold calls to hero in SB w/7 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img]. Hero calls. BB calls.
8 to the flop 16 SB. Flop: 6 [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img]
Checked to UTG who bets. One of the described above players calls in UTG +1. A LAG in UTG +2 raises. 3 next players call 2 cold. Hero? How about raise PF?
