Using the 1100 would work well in combination with a MJ1200 or two on a timer. The 1100 would provide a nice constant stream across the length of the tank and then the MJs on a wave timer would provide good current variation. Just a thought. Of course, I understand that TAAM is releasing a SEIO controller in the near future so you may want to factor that into your decision. Two 620s or 820s would work well too but they would cost more I think.
Also don't get your hopes up about the Seio controller it controls two pumps and controls them exactly the same and isn't able to alternate the power level to them. Price is also going to be about $200. Just something to think about, Tim
