What pump will I need?

[mark]

I'm about 12' horizontal, 10' vertical, 1.5" line

Started with a March 6 series (a big noisy beast, would of had no problem with the 60'), switched to Iwaki MD70 (great pump, no seals, easy 2000gph) now using a Barracuda (little quieter and a little less current draw than the Iwaki). Still in the box is a Velocity T4 (same as PS4, told they're silent, concern is flow will be around 800gph).

Had also considered a Dart. Was trading e-mails will Reeflo and they figured a Dart with a modified impeller I could probably get 1000gph.
