You focus should just be gripping so whatever is most comfortable, I tend to use an pronated grip with a straight bar, but I’ll prefer a bar that lets me use a neutral grip if possible. You’ll want to engage your lats to pull your shoulder blades together and down when you hang to take the load off your shoulders, so whatever grip helps you do that the most.
