best reflector for a 36" deep tank

[eran]

I am having a new tank being built at the moment that will be
72" * 34" * 24" . I am looking right now at the lighting and hope to get good coverage with new reflectors. I have talked with one of the reps at sunlight supply about the new lumenmax elites but he said that I wouldn't get full coverage in a 34" deep tank. He actually suggested the lumenmax 2's. He said that I would get better coverage and it is made out of the exact same material as the elites. What are your suggestions as far a other reflectors as well????

Lumenarc III regular size have very good coverage. If money isn't an issue and you plan to do topless Sfiligoi or Giesemann spectra is the two fancy fixtures you can get and it will cover 36".
