Even as a single driver autoxing in this area, where you can do 6 or 7 runs in a heat, you will find that the azenis will overheat after the third run if you are not spraying them with water. I would recommend the MX over the azenis, simply because they are more difficult to overheat. Unless you like understeer, I wouldn't go with the staggered setup either.
