Take this for what it's worth because I've never run one, although I'm familiar with their basic principles of operation.

First off, I am assuming that you intend to start with identical female clones.
Next, I'm wondering why you would add a SCROG to what is already a perfectly serviceable SOG (assuming, again, female clones). With an aero system, you will definitely want to make sure that you have access to the nozzles in case of clogs. So I would be a bit wary of adding a net. A good solid canopy is attainable just with healthy plants spaced appropriately.
Now when you say the spray bars are atop the table, I assume that the plumbing is primarily on top but the nozzles stick into the chamber? I'm trying to envision this.

And finally, what sort of grow background do you already have? Aero is like the Porsche of grow styles- rewarding and fast, but difficult to drive! Be ready for an adventure!
