I deal with one ways like that. In general, I stick to the right and pretty much take that lane. Considering most municipalities have a slow traffic to the right law, I think it makes sense to stay on the right. Easier to be in the right (according to the law) in case of a traffic accident. If I turn onto a one way with the intention of turning left onto another street within a pretty reasonable distance, then I'll take the far left lane so I don't have to try and play frogger across 4-5 lanes.
