How does leading out for roughly 1/2 the pot sound to make it look like we are pricing ourselves into the nut draw (when In reality we already have it). Tight passive guy might not be able to let go of that ace if he has one, and Laggy guy might decide to try and push everyone out due to the draw and your donk bet.

Edit:
Wait..that may look suspicious if we have a tight/passive image and are all of a sudden leading out. But IMO someone who is tight/passive probably wouldn't lead out the nuts so that's why I'd lead here.
