I'm running a T-5 6 light nova extreme pro with the stock Current USA bulbs and I'm getting really decent growth on my softies, LPS and SPS.
My tank is a 120g so it's about 4" shallower than yours, but if you had the ATI bulbs in a quality fixture you could run T-5's for sure.
I've got acros, montis, stags, birdsnest, anemones all doing fine with the lighting I have.
