I always lead out with my sets as well unless I have aggressive pre flop raisers or bluffing maniacs to act behind me. I guess thats why putting out big bets with strong draws works for me.

How do you play your made hands on draw heavy boards? If you were going to give a free card to a JT5 flop with two diamonds, you should probably re-evaluate how you play your made hands in this situation and not how you play your strong draws. Both hands should play pretty much the same way. You are trying to rep a strong hand on a draw-heavy board, when really you have the draw and are hopefully up against a not-so-strong made hand.
