I actually have the same set-up (10 gal with 96 w) that I am playing around with to eventually be my stony coral quarantine tank. In this tank I have gotten orange Montipora "digitata" to color up and grow. I havn't had the Acropora long enough to make any real claims to the 96w effectiveness but so far they have kept their color and look very healthy. I have grown in other tanks (36 gallon with 2 x 65 w pc) orange Montipora "capricornis", green Pocillopora, and Seriatopora. I have seen other people grow a small frag of Acropora sp. into a good size colony displaying amazing blue coloration in a 10 gallon under 96 watt powerquad pc. The tank is very shallow and the powerquads are pretty bright so I don't think you will be limited by the light.
First off please reallize that there is much more that goes into the health and coloration of stony corals than light. Also reallize that "sps" is a useless term that groups together many corals that don't necessarily have similar needs or do best in the same conditions.
As the others have stated I would start with an aquacultured frag of Montipora sp., Pocillopora sp., or Seriatopora sp., and see how they do. I have found the orange colored Montipora's and green colored Pocillopora to be some of the easiest to keep their coloration under a wide range of conditions. Once you do well with these you could try a frag of the Acropora that are sold as "green slimer" or "Acropora millepora" as these tend to be among the hardiest members of the genus Acropora. I would personally only put about 3-5 corals maximum in that size aquarium; all stony corals of similar needs and minimal aggression towards eachother using alleopathic compounds and sweeper tenticles (not to say coral competition and aggression won't be present).
