I have been experimenting with cooking BB's at 225-275 without foil. Do you guys (that don't foil) find that the BB's take longer to cook than using the 3-2-1 or 2-2-1 method? I went a solid 5-6 hours at about 225-240 and I still think they could have gone a bit longer. If it changes anything, I did mop every hour.
