I don't mind the parting rule, and wouldn't mind it going a bit further. Make the entire turn in box come from a single piece of meat/slab of ribs. Other than chicken of course.
In fact if you really wanted to turn this into a skills competition, allow only a single butt, a single brisket and a single slab of ribs to be cooked. Now.. you are testing the abilities of the pitmaster.
It takes much more skill to produce suitable turn in quality meat when you only have one shot at it.
