Howdy Y'all I got a big smoke coming up next weekend. I am wondering which would be best to use , lump or charcoal. i will be cooking 3 briskets totaling 38 pounds. I have an old hand - made grill ( 24x50 in.)that I put a 18x18x18in. smoke box on, also wondering about how long it might take to get the job done . Any feedback would be welcome .
