Loose-Aggressive Poker - How to play Any Two Cards successfully

I have occasionally encountered players at poker tournaments who play a very loose-aggressive game with great success. They are obviously pulling off alot of bluffs, but they also seem to easily know when to get out of the way and save chips. Some players seem to be able to play this style quite effectively without taking large swings to their chipstack.

Here's a question for the "loose" poker players: What advice can you offer to play the ATC (Any Two Cards) style successfully?

Postion is key for this style of play. Intimidation has to be subtle and timed properly. Gauging a player's hesitation is also useful. Also I try to "mix my pitches" when bluffing, sometimes quickbetting and sometimes long hesitation to keep other players off-balance.
