No question on this brisket the oil effected (right usage?) bark formation. There definitly was not the typical smoke ring, however, at closer examination (when I was sober) there was a dark outer layer on the brisket. I think this was from the dark rub and resting overnight vs. smoke ring.
At first I thought I might try it again using water, but now I really don't see any need as I was very pleased with the results as was everyone else. For me, smoke ring and bark are not a major issue, flavor is foremost. If you're a ring/bark person, I'd suggest using water.
It's interesting that Kevin wrote that oiled meats cook quicker, no question that this one did (which was a good thing).
