Lighting a planted 3x2x2ft tank

I'm trying to decide how full on to go with the lighting fixture for my new tank. I've calculated the WPG but I don't like to rely on that alone, coupled with the fact the tank is 3x2x2ft so it will be quite deep.

The tank will have ADA New Amazonia as the substrate and I plan on dosing liquid CO2 to start, with hopes of moving up to a proper CO2 setup sometime in the future (probably not for another 12 months or so). The tank will be heavily planted, and I'm aiming to try some medium to high light requiring plants.

With the lighting fixture I'm tossing up between 4 x 39w tubes, or 6 x 39w tubes. Obviously there's only so far I can go in terms of lighting before it becomes obsolete due to a lack of CO2.

Would love some advice from more experienced planted tank peeps, as all I've ever dealt with is fairly low tech setups.

Is going two Finnex Ray IIs out of the picture?

I have a RayII 30 inch on my 37 gallon which is 24 inches deep and I use an aqueon modular for supplemental as I am looking for medium light. However the 36" has more LEDs and a higher PAR value. It might be an option worth considering.

I have a Fugeray 36" on my 46 galloon and currently have a 24 inch T8 on the front(I know, it's laughable to some. I am looking for medium light on that tank as well. I may want to get a MonsterRay 24 for the front or maybe a 36" and put it just barely in front of the fugeray.
