Later this evening I will be putting two briskets into the MES 30. Hoping to serve around 4:00pm tomorrow. I plan on seperating point and flat to make burnt ends while I let the flat sit in a cooler packed with towels for 3 hours. How long should I anticipate for two 10 lb packers to get to 200 degrees? I know typically 1.5 hours per pound for one slab. Does time decrease for two slabs?
