Trying to add to my A51 setup

I currently run two SGS-160 units in a 32"x32"x6' tent.

I'm trying to figure out if there are any worthwhile lighting additions I can make to my space. I've seen a couple of grows where fluorescents were added for sidelighting

Any other good/proven options out there for supplementing my pair?

The A51-75 throws out some serious light. I run with two 160s, a 190, and a 75.
The 75 is nice as it has white and red just like the 160.
