I have T5 over my tank and couldnt be happier. I run the Sunlight Supply-Sun Blaze 48" 8 bulb fixture( only running 7 bulbs due to overhang) and I am allmost all SPS. The only complaint I have about this fixture is the are no built in fans, so I built my own fan rack using computer fans and they are dead quite.

T5's all the WAY!!!:lol:

the nova extreme pro's have either individual or one that is stamped into individual shapes, have not really looked but it is not one big parabolic. got a 6x39 used a month ago and i am happy with it so far. I think the aquamedic ones have some nice features too, not sure what the looks or cost of them is though.

thanks for the info, but I decided to take the plunge into the T5 world for real and purchased the TEK Elite 6x54w fixture.
We will see how things go in the months to come

lighting,
 

I have the same tank dimensions. I am using the nova extreme 6 bulbs, with KZ lights. Its been about a year and a half now. Its my first tank, so i cant offer any comparison. I have a toadstool and colt coral, also a bubble lps coral, a pulsing zenia, spaghetti leather and a clove polyp. All my corals doubled or trippled in size, within one year. I dont know if its solely due to the lighting. It could also be due to water quality althou when i test for phosphates, my reading is zero. I am happy with the fixture. To me, my corals are growing too fast. I would rather they grow less, so i can enjoy them more at their smaller size. My toadstool was 6 inches across when i purchased it, now its 14" The colt also was about 6-7 inches tall when i purchased it. now its 16" tall.
