Anyone else take this line?

[spydog]

UTG is weak and usually sees the turn no matter what. SB is a decent, but not outstanding player.

With such a ragged flop, I feel I'm ahead of many hands the SB might bet with PF and I feel there is a good chance he feels compelled to bet this flop because of his PF action. Is this a flop fold with 4 people or am I justified with this line of attack, considering my position on the SB?
