more ribs than usual?

[Guest]

i'll be making 10 racks of ribs, which means some will have to go on the bottom rack. I know the temp is different down there. How do you handle the difference? Switch them out halfway through?

Rotating will give you the best chance to get them all done at close to the same time, the bottom grate will run 15 to 25? cooler than the top grate.
