Cooked em today at 250 on the egg. I put them on at 1pm and figured they'd go five hours so I intended to start checking them at 5pm, four hours in. Turns out they were already not only done, but past done. I gave them a quick sauce and them slapped em on cookie trays and covered em with foil. They ended up decent in the middle, but dry on the ends and literally fell off the bone. Next time I'll either do them lower, at 225 or start checking them at 3 hrs.
Ironically the family loved them, I was the only critic.
