I've got a 1" sea swirl hooked up to a Barracuda. I know it's not exactly what you are looking to do, but it's close. No issues on my set up. The only thing I don't really like about my sea swirl is that you aren't supposed to pump more than 1000gph through it. I put a ball valve right before it so I could turn down the flow right at the sea swirl, and guesstimated the flow.
With 3 on a Dart I don't forsee a problem.
