Indirect heat for baby backs on a kettle

I'm cooking two slabs of baby backs on my 22.5" kettle tomorrow while the WSM will be slam full of pork butts. What is the best arrangement of charcoal/heat for indirect cooking in a kettle? Should I pile the coals on one side with the ribs on the other, or have a two sided fire with small piles on either end and the ribs in the middle? Obviously you take advantage of the full 22.5" diameter in the middle, and I don't plan on trimming the ribs back. I'm looking to maximize smokiness but also create a managable fire that requires little maintanence.

Yes, and because of this I split. It's habit though, you don't have to.

I took this pic before doing a flat, but its the same setup I use when doing ribs. It's hard to see, but the side of the charcoal basket is also foiled.
