Flopping a monster in a four way raised pot. Bet out or check?

Wow lots of responses. Thanks to everyone who posted.

Ok, a lot of people aren't in favour of limp-calling UTG here. Fair enough. I probably do usually raise with this 6-handed, but for some reason decided to limp.

My image is pretty much perfect, as I'd just been caught bluffing.

As you've probably guessed, I didn't extract any value, or else I wouldn't have bothered posting. I led out for 2/3 pot-ish looking to get raised by an overpair, but they all just folded.

I guess I could probably have got one bet out of it by checking, but as people have said, leading out was the only way to get his stack, and I'll do it again next time.
