I've never had issues controlling temps with lump in a UDS. The only explanation I can think of is I cooked a freaking lot of food in mine last summer, and it was sealed up like a freaking tank. No air leaks anywhere because of all the BBQ goo built up everywhere.
Right now, I have to put the UDS in the sun just to get the lid off, because all the BBQ gunk is keeping lid from releasing from drum. It's freaking tight!
Thanks. I did only have about 10 pieces of lit lump to start with, but you're right, it wasn't packed. I just poured a bunch in with a couple chunks of apple. Unfortunately, I was out of briqs. I'm going to stick with briqs and maybe use lit lump to get the minion method going faster.
