The Stingrays puts out awesome flow. The Dolphin 2100 :) is quieter than the Stingray . I tested my system today with both pumps side by side in my garage. The Dolpin throttled down easily with a Gate Valve enough to run my SCWD. Both pumps perform really well. I just know that the Stingray is a makes a little more noise. I know that the Stingray has been transformed into the Barracuda this year. The Barracuda has a much more quieter than Stingray due to the new housing. I would bet that the Barracuda is going to be tuff to beat for price and performance.
Thats my opinion.

Hope this helps..

how's the heat transfer with those pumps Ed? I would think they cut corners somewhere (I hope not, but...) to get the costs down.

I just put my hand on both pumps. The external case of the Sequence pump is hotter than the Dolphin. I put a digital Thermometer inside the tank. The tank temp is 77 degrees with out a heater. It has been running for about 4 hours with new water in it. I added my UV sterilizer to the tank plumbing.
