Meso Farming Spots Post BB

Since we've agreed on the meso power of Windraiders, what map and what cycle process do you all suggest? Originally, I remembered Tornado Corridor being great EXP on my pre-BB I/L Mage, but now, after testing, I can blow through the entire map and run an additional monsterless lap before spawn even occurs. As a result I've gone to Lower Ascent but there's a bunch of backtracking necessary, are any of the cave maps better, should I CC through multiple channels?
