On my stealhead plug rods I run Abu 5501's. I count the passes of the level when running out the plugs. I run my hotshots, wiggle warts or what ever plug Im using out 3 to 6 passes, depending on the water.
As for rigging a kwik fish. I always use a jet diver in front of a kwik fish. A #30 jet diver on an 18" dropper rigged sliding. I use a 3' leader to the plug. This will keep the plugs down in slow and fast water both.
