Flopping bottom two on draw heavy board OOP

[FreakDaddy]

In a big field like this, I go back and forth with what the best play is. Being beat already is fairly unlikely, but somewhat possible in a donkish field. Is it better to just check/call, or lead this kind of flop or even over bet it? You know you're going to get lots of calls here. What's your best line?
