2nd attempt went much better. left the skin on this time (more on that below) and applied a basic rub, then smoke on low heat (250). after two hours it looked like this:
poured a beer in the pan and wrapped in foil. 3 hours later:
raised heat to 300-ish, uncovered and basted for the last hour:
it was really good:
the skin probably helped keep it moist, but had a bit of a rubbery texture (probably needs higher heat to crisp), so i would remove it before cooking next time, and probably cut back the braising time by ~hour (it was tender, failling apart, but perhaps slightly overdone).
still, a huge improvement on the first attempt.
