NL200 - Combo draw play.

[BeatPurdue]

To become less predictable, I have been trying to play my combo draws the same way I would play a set. Problem is, I continue to run into sets when I do this. I would really like some input on the hand below. I feel there is a strong chance that villian (no reads) has a set here. Even if I think he does have a set, I shouldn't fold this, should I?

Is this how I should play almost all of my combo draws?
