Which defensive line abilities to use in 6-1?

Recently switched over to 6-1 and am absolutely in love with it so far.

Right now I’m using Barry with Edge Threat, DON, and Under Pressure and Hirsch with Edge Threat Elite on the outside edges, and they are pretty insane with their speed when sending six.  My question is are the pass rushing abilities even really worth it at outside linebacker when they are coming in without getting blocked?  Wondering if I should move around some pieces and just run Under Pressures on the two outside guys?  Also curious if Edge Threats would activate on the defensive ends on the line.  Appreciate any input!
