The more I write, the less of a fan I become of Third Party Omniscient. It feels strange to focus on one character for 90% of the chapter while making only a few remarks to portray OOC knowledge. If I want to get inside another character's head, I just do alternating Third Party Objective, switching focal characters at chapter or section breaks.
I don't have nearly the whimsy required to pull of Third Party Omniscient.
