Since the question was asked: I use MCP actions found HERE. I have the "All in the Details" set. I mainly use the "Soft Color" action, and the "Touch of Light, Touch of Darkness" action (which is free and can be downloaded from the MCP website). I'll sometimes use the "Binoculars" or "Telescope" actions, the "Quiet the Noise" action, and "In Stark Contrast" action. It all depends on the photo, and what I'm trying to achieve.
I hope that helps :)
