I too am new to my UDS, this thread will help me as well. I used lump, just dumped it in the coal basket and was having a hard time keeping temps below 250*. I will now try stacking the lump and start with a little less in the chimney. Also in the future I'll try a bag of Stubb's that I have heard a ton of positives about in this forum. I hope the briquettes will burn a little cooler enabling me to use the air inlets a bit more for better control.
