You can aim a LOT more with RW then the WAV so keep that in mind as you look at your rockwork and such. The WAVs are limited in angle. While they have some it is limited. I found it to be perfect amount when on the side glass for my setup though.
Seeing the new gyre controller and line out if I were to do it now I would have 2 gyre 150 (which is now 230 I think) and 2 PP8 on the back wall to clean up deadspots. Run the gyres at antisync with periods of them both on to smash water into one another and add confusion and you have a great setup.
