Lots of variables to consider. If you CL the Dart and add too much head, the flow volume will be poor. Depending on how you plumbed the Barracuda you could end up with too much localized velocity but good flow volume. I think what you are shooting for is maximum flow volume by controlling head loss while controlling velocity so you don't blow stuff all over the tank.

Example. If you plumb a Dart to an OM 4-way with all 1 1/2" pipes, head loss is low and volume is good. If you use a V1 drum (1 open at a time), flow velocity is almost too much and you've added a lot of head loss.. V2 drum (2 open at a time) makes for better velocity while maintaining flow volume because there's less head loss.

Make any sense???
