Do you get more airflow with directional vane vs straight vane rotors?

Directional vanes flow more then straight. Straight generally more then post vane.
The '99 to '04 use a post vane, actually a modified post vane which is an interesting design. The '05+ use a straight vane. The pictures below from my Webshots shows the difference.

There is some discussion which cools better, the post vane with more vane surface area or a straight vane pumping more air. The '99-04 use the normal posts but interspersed with other posts that are shaped as vanes to pump more air.
