You didn't mention you were focused almost exclusively on SPS. In general 6095 is the way to go, if you can wait, for a tank of this size, a mixed tank, softy tank, LPS tank, anemone tank. For a high flow SPS tank, the 6105 would be better suited, especially as things grow in. The 6095 almost exactly mimics the wide flow of our competition, it is for people who want that flow, it also has a smaller footprint. I don't believe it is the best type of flow in all cases, certainly many SPS would benefit from a more forceful flow.
