Just got my BGE and plan to smoke a boston butt ( 8 lbs) for the superbowl. I am familiar with WSM, but wanted to switch as the WSM is too much maintenance for a long cook. My usual cook times on the WSM were 10 to 12 hrs at 250. Many of the posts here seem to indicated the BGE cook time of 16 to 20 hrs. Is the cooking time due to the difffernce in technologies or am i missing something?
