Ah. What kind of corals do you want? For a mixed reef I think you'll be fine, but if your going heavy SPS I would go with a Hammerhead for at least one of the closed loops or go with all 3 darts on a closed loop.
On my 75 I have one dart on a closed loop and a mag 5 return for a total of 41 turn over / hour. For a tank four times the size of mine, I would try to match that.
