califishdude,
IMHO you are putting the cart before the horse. I see your tank inhabitants do not include corals yet. Is this your reason for the lighting upgrade? Will you be adding corals?
I would have a least a game plan on what types of corals I wanted to keep. Then I would research their requirements and THEN decide on the lighting issue.
There are are great many corals that cannot survive under MH, but on the other hand there are just as many that cannot survive without it.
If you decide on the MH, I would go with the VHO combination. Every one has their own color spectrum and I like this best on my corals. But then again I like a little more blue.
HTH
