You would have to have BHs at the return holes to keep water from draining in/out at those lower points below the teeth.
The drains look like 3/4" and 1"?
I think I would go with a durso because of the return holes/BHs and because if you ran a herbie, you would need to run an "over the top" return line that would take away from the clean look of the rimless tank. If you want to run a higher flow drain/return, you may need to install a reverse durso as well at the drain output to the sump to keep the noise down. If you keep the flow rate from the return low, you should have no problem keeping it quiet. I don't see you running more than 400 to 500 gph from the return and a 1" durso drain is more than capable of handling that. As long as you account for the air mixing with water as it pulls down the drain, you should stay quiet.
