Hello recently picked up a big steel keg and have been cooking with lump so far ,been doing some reading about briquette's ,do any of you guys or gals use them?if so in combination with the lump or just by itself.If i understand what i have read you light your briquette's and leave them till them till there grey colored,then add the lump around the pile of briquette's?thx for any info, appreciated.....bob
