BAD Board, BAD Position, GREAT Hand...HELP!!!

[MeanGreenTT]

$3r/a Sat to 500k, just started level 9, barely 2 hours into the game. I'm, below average by a few thousand. Just recently moved to the table so no real reads, big stacks were limping a lot of hands, nothing unusual. Here goes:

PokerStars No-Limit Hold'em Tourney, Big Blind is t600 (9 handed) internettexasholdem.com

Button (t22555)
SB (t19619)
Hero (t14050)
UTG (t10313)
UTG+1 (t25795)
MP1 (t67024)
MP2 (t29066)
MP3 (t25495)
CO (t11750)

Preflop: Hero is BB with 4[img]/images/graemlins/diamond.gif[/img], 3[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls t600, <font color="#666666">1 fold</font>, MP2 calls t600, <font color="#666666">3 folds</font>, SB completes, Hero checks.

Flop: (t2500) 5[img]/images/graemlins/spade.gif[/img], 7[img]/images/graemlins/club.gif[/img], 6[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">SB bets t2400</font>

Hero???

Ok, I've flopped the 2nd nuts AND the sb has led out, making a pot sized bet. He's got 3 players to act behind him and 2 have him covered and've been active. He's obviously looking to price out the flush draws, and I'm sure with 4 of us in, 1 of the 'em could very well be on it.

Now unless he's leading out on the flush draw himself, I have to put him on 2 pair or the set. NONE of which really matters much, 'cause I'm playing these nuts [img]/images/graemlins/grin.gif[/img]

There's T5k in the middle after the sb leads out, the ONLY question is how much to bet.

A "normal" raise would leave a little better than 2-1 odds (calling 5k on a 12k pot) on the call, and if either of the big stacks come along, the sb'll be more than priced in...not to mention it'd leave about 1/2 my stack behind.

So, make a raise to ~7500 or is this a push?

Thanks in advance!
