Howdy--- I have been signed up to cook 4 boneless butts (about 6 lbs each) to be done at 12 tomorrow. I have lots of experience with bone-in and my average cook time is around 18 hours (at ~225) to get to 195. I have a large egg and will either try to get them on one level or use the Woo3 Extender for two levels.
My questions are: Should I tie tie them up (to make them more butt-like? How much of a time adjustment should I make for the boneless factor? I would typically get things going at 9 or 10 at night to have them ready late afternoon the next day. At 18 hours that would mean putting them on at 6PM, but if I shaved a few hours off, I could still put them on at 9 tonight. My phobia is always not having things done in time.
