So I thought I'd follow-up with some pr0n.
Cooked it in my 18.5" WSM 2.75 hours unfoiled over hickory wood & charcoal, then foiled it and cooked for about 1.5 hours more, then unfoiled and sauced for about 45 more minutes. All in all I probably overdid it a bit, it could have been a bit moister, but it was really tasy and just like... slid off the bones. That top part (and the solo bone) just came apart when I was taking it off the grill. Bend test indeed.
