I can't say I'm versed enough in reefing to answer all your questions above, but I can tell you that I recently modded my light to go from PC's to T5HO and it was by far the best thing I've done for my tank. In combination with my MH, I can now really adjust my lighting look and get the "pop" that I wanted out of my corals. T5HO is the way to go in my humble opinion.
