I have two Hydra 26 over a 75 with minimal rockwork. If you're not running a SPS dominant tank, you should try just the 32s out before spending more on blades.
I also have a 12" Blade Grow over a 20 gallon tall RBTA tank. The old school blue & white look reminds me why hydras and radions took over the market. Hopefully the Glow has better color and I wouldn't recommend the Grow for fill lighting on Hydras unless you only use blue and white channels on them.
