@Matt_T, I enjoyed using the butcher paper. It made clean up a breeze after trimming the meat and I think it actually help maintain the bark. Much to my surprise was the butcher paper actually retaining
some most of the drippings. As the paper is heated it becomes brittle and what almost seems impervious; unfortunately when removing the paper before wrapping in foil to rest (while my brisket finished), I lost a lot of drippings. By that point by drip beans were already removed so perhaps next time I'll have a tray down there.
