NL50: Flopped the nuts in multi-way pot - how's my line?

[slickss]

What do you think of my line here? My logic is that I'm pretty sure someone has flopped a strong two pair or even a set and will call. At this level I could even get called by something as weak as AT - "top pair and nut draw".

I am wondering whether you think this is strong or just scared?
