On a gph/watt basis, it's hard to argue against a high flow Sequence Dart on a closed loop.
I don't understand the suggestion to use a pressure rated pump like the Iwaki unless you're planning on running eductors. IMO, you want a tank that maximzes flow at low head pressure, not a pump that's capable of delivery good flow at high head pressure.
