I have kept SPS under an LED Radion in a NC28 for a year now, but not exactly what you are looking for. I have seen quite a few examples of SPS doing well under the stock Advanced 89w hood, but they are all fairly new tanks so no comment on long term success. From what I have seen, color and growth are good, but it's easy to make these claims after 1-3mo of growing a frag...
What I can say is that LED will give you great growth and color, given you are getting the right intensity, coverage, and spectrum. I'm actually tempted to try an MH over my tank for a year to see if there is any difference and give actual and factual data to the argument, but thinking about giving up the sleek form factor of the Radion and the abundance of controlability is a huge deterrence.
